Abstract: The aluminate phosphor, Ce0.67Tb0.33MgAl12O20.5, has been synthesized by the combustion of mixtures of respective metal nitrates and urea. The process is energy saving, instantaneous and safe. The reaction can be completed at 600℃ furnace temperature, which is much lower than that used in traditional solid-state reaction process. The phosphor was characterized by XRD, SEM, fluorescence spectra, particle size distribution, density and relative brightness measurements. The effects of different preparation conditions on the properties, especially the brightness, of the phosphor were inspected.

Key words: combustion synthesis, aluminate, phosphor, rare earth
