摘要：
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 mu m 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.
