:0.10Eu

0.06Mn phosphor was synthesized at 800~1 100℃ by using MCM-41 as Si source. The influence of calcination temperature on the luminescent properties was investigated. The results indicate that the intensity and bandwidth of Eu

blue-green emission increase with temperature at first and then decrease. The sample calcined at 1 000℃ has the highest Eu

emission intensity. The peak maximum shows red-shift from 450 nm to 480 nm when the calcination temperatures changed from 800℃ and 900℃ to 1 000℃ and 1 100℃. The red emission of Mn

arises from the excitation by the Eu

emission and increases with temperature. The Eu

ions which can transfer energy to Mn

are mainly on the ten-coordinated M(1) sites.
