离子的

跃迁）激发下发出单色性较好的红色荧光，相应的色坐标值为（0.613 6，0.337 7），色纯度为85.5%，量子效率为0.36。随着Eu

phosphors were synthesized by hydrothermal method and after heat treatment conditions. SEM images show that the samples are composed of some long rod shape and irregular polyhedron structure

and the average particle sizes are about 0.6 and 2 m

respectively. The samples can be excited efficiently by 394 nm (corresponding to the

transition in Eu

) and emit red fluorescence with better monochromaticity. The color coordinate of the red fluorescence is (0.613 6

0.337 7)

and the color purity is 85.5%. The luminescence intensity increases with the increasing of Eu

concentration. Part of the phase change occurs when Eu

mole fraction is more than 7%. Thermal quenching measurements show that the relative brightness and red ratio of the samples are stable to the change of the temperature in the range of 37-100 ℃.
