Abstract: By applying combustion process with urea as the fuel, the precursor powders of the phosphor were obtained. After the heat treatment to the precursor powders, YAG:Tb phosphor was synthesized. The characteristics of the phosphor were determined by XRD, SEM and PL spectra techniques. The chemical purity of the phosphor was greatly improved though no flux added to the phosphor. The particle sizes of the phosphor were fine (1-2μm) and well-distributed. The luminescent properties of YAG:Tb and YAG:Ce,Tb were analyzed.

Key words: combustion synthesis, Y3Al3O12, Tb3+ ion, phosphor
