Synthesis of YAG:Tb by the citrate gel process

Ultrafine terbium-doped yttrium aluminum garnet (YAG:Tb) phosphor powders are prepared by a nitrate–citrate sol–gel process using 1:1 ratio of citrate/nitrate. X-ray diffraction (XRD) and Fourier transform infraredspectroscopy (FTIR) were used to investigate the structure and morphology of powders. XRD and FT-IR results showedthat the products well-crystalline when treated above 850 °C. In addition, partially crystalline YAG phase was observedat 750 °C.
