摘要：

A novel ceramic synthesis technique, combustion process was investigated for the production of phosphor powders. In this study, we have developed a new method to product phosphor powders, and applied this process into two materials fabrication. Y3Al5O12:Ce and Y2O3:Eu phosphor powders were successfully synthesized by combustion process. The process takes only 15 min to obtain Y3Al5O12:Ce and Y2O3:Eu phosphor powders. The resultant phosphor powders were investigated by X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), photoluminescence excitation and emission spectra (PL), scanning electron microscope (SEM), and transmission electron microscopy (TEM). The results revealed that the formation temperature of phase is significant low, compared to solid-state reaction route of constituent oxides. (c) 2007 Published by Elsevier B.V.
