Abstract
Light modules for converting the wavelength of light are described herein along with methods for using and making such modules and devices incorporating such modules.
Claims21
A light module comprising:
- a first substrate;
- a conversion layer adjacent to the first substrate and contacting the first substrate, the conversion layer comprising a plurality of quantum dots/nanocrystals dispersed throughout a matrix material, each quantum dot/nanocrystal having an inorganic outer coating, selected from silicon monoxide, silicon nitride, or a combination thereof, covering the outermost surface of the quantum dot/nanocrystal;
- and
- a second substrate adjacent to the conversion layer and contacting the conversion layer on a surface opposite the surface contacting the first substrate.

An optoelectric device comprising:
- a light source capable of producing light having an input wavelength;
- a light module comprising:
- a first substrate;
- a conversion layer adjacent to the first substrate and contacting the first substrate, the conversion layer comprising plurality of quantum dots/nanocrystals, each having an inorganic outer coating covering the outermost surface of the quantum dot/nanocrystal, dispersed within a matrix material and being capable of converting the input wavelength to one or more different wavelengths of outgoing light;
- wherein said inorganic outer coating is selected from silicon monoxide, silicon nitride, or a combination thereof and
- a second substrate adjacent to the conversion layer and contacting the conversion layer on a surface opposite the surface contacting the first substrate.
