摘要：
Eu2+-doped Ba3Si6O12N2 green phosphors were prepared by microwave assisted sintering method at 1275 degrees C for 4 h, while the counterparts using conventional solid-state reaction method were synthesized at temperature higher than 1300 degrees C and for to 10 h. Microwave assisted sintering could reduce the activation energy and enhance the diffusion rate, thus greatly improved the sintering. Moreover, the influence of Si3N4 content on phase formation, morphology, absorption, and quantum efficiency, and photoluminescence properties of phosphors were studied. As a result, the Ba3Si6O12N2:Eu2+ samples sintered by microwave assisted sintering method have a higher phase purity and photoluminescence intensity under ultraviolet excitation as compared with samples sintered in the conventional tube furnace. The proposed method is a potential preparation method for the oxynitride phosphors with strong photoluminescence and high phase purity.
