采用糖热法制备了高浓度YAG：Ce 3+纳米粒子组成的透明色转换厚膜，并对其光学性能进行了表征。纳米颗粒含量为70.7wt%的200 μ m厚的膜在对应于YAG：Ce 3+的发射峰的525 nm处的透射率为82%。通过在透明膜的背面放置反射镜，由于YAG：Ce 3+纳米颗粒中的Ce 3+的5d -> 4f跃迁的光致发光强度加倍。从该结果判断，YAG：Ce 3+纳米颗粒的透明膜具有显著低的散射损耗。
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.
