Abstract

An method for making a shielding assembly includes the steps of: forming a plurality of active layers, wherein each active layer of the plurality of active layers includes a base material and a fluorescent molecule; and forming a multi-layer laminate including the plurality of active layers.

First claim

What is claimed is:

1. A method for making a shielding assembly comprising the steps of:
forming a plurality of active layers, wherein each active layer of said plurality of active layers comprises a base material and a fluorescent molecule; and
forming a multi-layer laminate comprising said plurality of active layers, wherein said multi-layer laminate is configured to successively shift, through each one of said plurality of active layers, electromagnetic radiation from a visible portion of an electromagnetic spectrum to a non-visible portion of said electromagnetic spectrum.

2. The method of claim 1 , wherein said forming said plurality of active layers comprises selecting a unique fluorescent molecule for each active layer of said plurality of active layers.

3. The method of claim 1 , wherein forming said multi-layer laminate comprises applying said plurality of active layers to a substrate layer.

4. The method of claim 1 , wherein said multi-layer laminate is configured to:
absorb electromagnetic radiation having an initial wavelength in said visible portion of said electromagnetic spectrum;
progressively shift an incoming wavelength to an outgoing wavelength as said electromagnetic radiation successively passes through each one of said plurality of active layers, wherein said incoming wavelength of a succeeding one of said plurality of active layers is equal to said outgoing wavelength of a preceding one of said plurality of active layers; and
emit said electromagnetic radiation having a final wavelength in said non-visible portion of said electromagnetic spectrum.

5. A method for making a shielding assembly configured to absorb light having a wavelength and to emit light having a different wavelength, said method comprising:
forming a first active layer comprising a first fluorescent composition configured to absorb light having a first wavelength and emit light having a second wavelength that is different than said first wavelength;
forming a second active layer, adjacent to said first active layer, comprising a second fluorescent composition configured to absorb light having said second wavelength and emit light having a third wavelength that is different than said first wavelength and said second wavelength; and
forming a multi-layer laminate from said first active layer and said second active layer.

6. The method of claim 5 , wherein forming said multi-layer laminate comprises coupling said first active layer and said second active layer together.

7. The method of claim 5 , wherein:
said second wavelength is longer than said first wavelength; and
said third wavelength is longer than said second wavelength.

8. The method of claim 5 , wherein said first wavelength is in a visible portion of an electromagnetic spectrum.

9. The method of claim 8 , wherein said third wavelength is in a non-visible portion of said electromagnetic spectrum.

10. The method of claim 5 , wherein said first fluorescent composition and said second fluorescent composition each comprises a styryl dye.

11. The method of claim 5 , wherein said first fluorescent composition and said second fluorescent composition each comprises a styrylpyridinium molecule.

12. The method of claim 5 , wherein said first fluorescent composition comprises a fluorescent molecule comprising excitation and emission characteristics in response to light having a wavelength within a range from about 430 nm to about 520 nm.

13. The method of claim 12 , wherein said second fluorescent composition comprises a fluorescent molecule comprising excitation and emission characteristics in response to light having a wavelength within a range from about 500 nm to about 625 nm.

14. The method of claim 5 , wherein:
said first fluorescent composition comprises a first fluorescent molecule, having excitation and emission characteristics in response to light having said first wavelength, combined with a first base material; and
said second fluorescent composition comprises a second fluorescent molecule, having excitation and emission characteristics in response to light having said second wavelength, combined with a second base material.

15. The method of claim 14 , wherein at least one of said first base material and said second base material is transparent.

16. The method of claim 5 , further comprising coupling a substrate layer to said first active layer to form said multi-layer laminate from said first substrate layer, said first active layer, and said second active layer.

17. The method of claim 16 , further comprising forming a third active layer, adjacent to said second active layer, comprising a third fluorescent composition configured to absorb light having said third wavelength and emit light having a fourth wavelength that is different than said first wavelength, said second wavelength, and said third wavelength.

18. The method of claim 17 , further comprising coupling said third active layer to said second active layer to form said multi-layer laminate from said first substrate layer, said first active layer, said second active layer, and said third active layer.

19. The method of claim 18 , further comprising coupling a second substrate layer to said third active layer to form said multi-layer laminate from said first substrate layer, said first active layer, said second active layer, said third active layer, and said second substrate layer, and wherein said first active layer, said second active layer, and said third active layer are located between said substrate layer and said second substrate layer.

20. The method of claim 16 , further comprising:
forming a third active layer comprising a third fluorescent composition configured to absorb light having said third wavelength and emit light having a fourth wavelength that is different than said first wavelength, said second wavelength, and said third wavelength;
forming a fourth active layer, adjacent to said third active layer, comprising a fourth fluorescent composition configured to absorb light having said fourth wavelength and emit light having a fifth wavelength that is different than said first wavelength, said second wavelength, said third wavelength; and said fourth wavelength; and
coupling said third active layer to said fourth active layer, coupling a second substrate layer to said third active layer, and coupling said second substrate layer to said second active layer to form said multi-layer laminate from said first substrate layer, said first active layer, said second active layer, said second substrate layer, said third active layer, and said fourth active layer.
