Influence of ignition temperature on the morphology and luminescent properties of nano BAM blue phosphor

The Eu2+ activated blue emitting BaMgAl10O17:Eu2+ (BAM) phosphor was successfully prepared by solution combustion method. The Influence of ignition temperature on the morphology and luminescent properties of BAM blue phosphor was mainly investigated. The results show that When ignition temperature is low, the mixture reacts very slowly and the combustion is not sufficient leading to the final products including organic impurities and decreasing the luminescent intensity of BAM. But, if the ignition temperature is too high,the morphology of BAM will be destroyed. The optimal ignition temperature is 600℃, at which the obtained BAM has a regular spherical shape, narrow size distribution and high luminous performance.
