摘要：

Green oxynitride phosphors Ba3Si6O12N2 were prepared with metallic ratio of Si/Ba = 3. It was found that the nonstoichiometric mixture at Si/Ba = 3 formed the Ba3Si6O12N2-type phase easier than the stoichiometric one at Si/Ba = 2 after it was fired at 1200 degrees C for 5 h under a diluted hydrogen flow (5%H-2-95%N-2). The excess Si source led to a formation of SiO2 glass, which can act as a flux in case of formation of Ba3Si6O12N2.
