Patent ID: 7960721

Claim:
A light emitting device for emitting light having a wavelength, comprising: a substrate layer; a first injection contact positioned over the substrate laver; a first dielectric layer positioned over the first injection contact; a light emission layer positioned over the first dielectric layer, the light emission layer including a nanoparticle layer, wherein the nanoparticle layer comprises a plurality of templates, each template comprising at least one first binding site and at least one second binding site, the first binding site having a specific binding affinity for a first nanoparticle of a first material, the second binding site having a specific binding affinity for a second nanoparticle of a second material, wherein the templates are selected to include, in percentages, x first binding sites and y second binding sites; a plurality of the first nanoparticles bound to respective first binding sites; a plurality of the second nanoparticles bound to respective second binding sites; wherein the templates are assembled such that the first material and the second material form an alloy at a stoichiometric ratio of x:y, and wherein each template is a biological template, which is a biological scaffold fused with the first peptide sequence and the second peptide sequence; a second dielectric layer positioned over the light emission layer; and a second injection contact positioned over the second dielectric layer.
