采用液相共沉淀法,在1050℃煅烧合成了纯相Cex：Y3-x Al5 O12( Cex：YAG)纳米荧光粉。荧光粉的发射峰位于526.6 nm附近,吸收峰位于454 nm附近。当x=0.04时,发现荧光粉的发射强度最大。荧光粉的粒径大约为100 nm,呈现棒状或椭球状。结果表明此荧光粉适用于GaN基底白光LED。

The Cex:Y3-xAl5O12(Cex:YAG) fluorescent nanoparticals were prepared by the co-precipitation method. XRD analysis showed that the pure YAG phase could be achieved when calcination temperature was 1050 ℃. The phosphors had a broad emission band peaked at 526. 6 nm and a broad excitation band peaked at 454 nm. The highest luminous intensity of the nanopowders was found when x=0. 04. The size of the nanoparticle was about 100 nm, which presented the shape of axiolitic or stick. It was suitable for the application of white LED.
