Abstract

A material for an electronic device includes a substance arranged to emit light in a predetermined range of wavelength upon receiving an excitation energy, wherein the substance includes a plurality of carbon nitride particles and a siloxane material. A method of producing the material and a light emitting device including the material are also described.

First claim

The invention claimed is:

1. A material for an electronic device, comprising: a substance arranged to emit light in a predetermined range of wavelength upon receiving an excitation energy, wherein the substance is bio-compatible and includes a plurality of carbon nitride particles and a siloxane material; wherein the plurality of carbon nitride particles and the siloxane material share an amide linkage such that the plurality of carbon nitride particles is connected to the siloxane material.

2. A material in accordance with claim 1 , wherein the predetermined range of wavelength includes a range of wavelength visible to human eye.

3. A material in accordance with claim 2 , wherein the light emitted by the substance is in white color visible to human eye.

4. A material in accordance with claim 1 , wherein the excitation energy includes a photon excitation.

5. A material in accordance with claim 4 , wherein the excitation energy includes ultra-violet light.

6. A material in accordance with claim 5 , wherein the photon excitation has a range of excitation wavelength of 345 nm to 365 nm.

7. A material in accordance with claim 4 , wherein the photon excitation is at least partially absorbed by the plurality of carbon nitride particles and/or the siloxane material.

8. A material in accordance with claim 1 , wherein the plurality of carbon nitride particles includes C 3 N 4 particles.

9. A material in accordance with claim 8 , wherein each of the plurality of carbon nitride particles is of a size in a range of 1 nm to 1000 nm.

10. A material in accordance with claim 1 , wherein the siloxane material includes N-(β-aminoethyl)-g-aminopropylmethyldimethoxysilane.

11. A material in accordance with claim 1 , wherein each of the plurality of carbon nitride particles and a siloxane material is arranged to at least partially contribute the light emitted by the substance.

12. A material in accordance with claim 10 , wherein the plurality of carbon nitride particles is arranged to contribute a first emission spectrum of blue color within the predetermined range of wavelength of the light emitted by the substance.

13. A material in accordance with claim 12 , wherein the siloxane material is arranged to contribute a second emission spectrum within the predetermined range of wavelength of the light emitted by the substance such that the light emitted by the substance is in white color visible to human eye.

14. A material in accordance with claim 1 , wherein at least one of the plurality of carbon nitride particles is functionalized by the siloxane material.

15. A material in accordance with claim 1 , wherein the substance is a solid.

16. A material in accordance with claim 1 , wherein the substance is flexible.

17. A material in accordance with claim 1 , wherein the substance is adhesive.

18. A material in accordance with claim 1 , wherein the electronic device is a light-emitting device or a sensor.

19. A light emitting device, comprising a light emitting element arranged to emit an excitation energy; and a material having a substance arranged to emit light in a predetermined range of wavelength upon receiving the excitation energy, wherein the substance is bio-compatible and includes a plurality of carbon nitride particles and a siloxane material; wherein the plurality of carbon nitride particles and the siloxane material share an amide linkage such that the plurality if carbon nitride particles is connected to the siloxane material.

20. A light emitting device in accordance with claim 19 , wherein the light emitting element includes a light emitting diode.

21. A light emitting device in accordance with claim 19 , wherein the substance is a thin film at least partially covering the light emitting element.
