Abstract

A pre-polymer formulation comprising quantum dots and a precursor for a polymer having a free volume parameter VFH2/γ with a value less than or equal to 0.03 cm3/g is disclosed. A pre-polymer formulation comprising quantum dots and a cyclohexylacrylate monomer is further disclosed. Also disclosed are a quantum dot composition including quantum dots dispersed in a polymer matrix, the quantum dot composition being prepared from a pre-polymer formulation comprising quantum dots and a precursor for a polymer having a free volume parameter VFH2/γ with a value less than or equal to cm3/g; a method; and other products including a quantum dot composition described herein.

First claim

What is claimed is:

1. A pre-polymer formulation comprising:
quantum dots;
an adhesion promoter, wherein the adhesion promoter comprises a UV light curable optically transparent acrylic based material having adhesive properties; and a
cyclohexylacrylate monomer.

2. A pre-polymer formulation in accordance with claim 1 wherein the UV light curable optically transparent acrylic based material a comprises bis[2-(methyloyloxy)ethyl]phosphate.

3. A pre-polymer formulation in accordance with claim 1 wherein the UV light curable optically transparent acrylic based material comprises a methacrylate monomer base structure including a phosphate functionality.

4. A pre-polymer formulation in accordance with claim 1 wherein the UV light curable optically transparent acrylic based material comprises an acrylate monomer base structure including a carboxylate functionality.

5. A pre-polymer formulation in accordance with claim 1 wherein the formulation includes the adhesion promoter in an amount greater than 0 up to about 10 weight percent of the formulation.

6. A pre-polymer formulation in accordance with claim 1 further comprising scatterers.

7. A pre-polymer formulation in accordance with claim 6 wherein the formulation includes the scatterers in an amount of 0.01 to about 15 weight percent of the formulation.

8. A pre-polymer formulation in accordance with claim 1 further comprising a thixotrope.

9. A pre-polymer formulation in accordance with claim 8 wherein the formulation includes the thixotrope in an amount greater than 0 up to about 15 weight percent of the formulation.

10. A pre-polymer formulation in accordance with claim 1 further comprising a photoinitiator.

11. A pre-polymer formulation in accordance with claim 10 wherein formulation includes the photoinitiator in an amount of about 0.01 to about 10 weight percent of the formulation.

12. A pre-polymer formulation in accordance with claim 1 wherein formulation includes quantum dots in an amount of about 0.01 to about 25 weight percent of the formulation.

13. A pre-polymer formulation in accordance with claim 1 further comprising an emission stabilizer.

14. A pre-polymer formulation in accordance with claim 13 wherein the emission stabilizer comprises at least one of potassium dodecyl phosphate and trioctyl phosphine oxide.

15. A pre-polymer formulation in accordance with claim 13 wherein the formulation includes the emission stabilizer in an amount greater than 0 up to about 10 weight percent of the formulation.

16. A pre-polymer formulation in accordance with claim 1 further including a cross-linking agent.

17. A pre-polymer formulation in accordance with claim 16 wherein the formulation includes the cross-linking agent in an amount of about 0.5 to about 15 weight percent of the formulation.
