Abstract

The authors produced the transparent color conversion thick film which is composed of a high concentration of YAG: Ce3+ nanoparticles prepared by glycothermal method, and characterized its optical properties. The transmittance of the 200 μm thick film with the nanoparticle content 70.7 wt % was 82% at 525 nm corresponding to the emission peak of YAG: Ce3+. The intensity of photoluminescence due to the 5d→4f transition of Ce3+ in YAG: Ce3+ nanoparticles was doubled by placing a reflection mirror at the back of the transparent film. Judging from this result, the transparent film of YAG: Ce3+ nanoparticles has markedly low scattering loss.
