Preparation of yttrium aluminum garnet doped with cerium for application in optoelectronics

Abstract

A sol-gel method has been developed to prepare pure yttrium aluminium garnet, Y/sub 3/Al/sub 5/O/sub 12/ (YAG), doped with cerium. The XRD pattern of the powder calcinated at 1100/spl deg/C shows the formation of single phase nanocrystal garnet materials with good performances provide by emission spectra of white light LEDs using these phosphors.
