The Process Condition Research of SrAl2O4:Eu2+, Dy3+ Luminous Powder by Microwave Method
The luminescent material,composed of rare-earth-doped alkaline earth aluminate,has been paid wide attention because of its chemical stability,usability and non-radioactive.In this study,the luminous material SrAl2O4:Eu2+,Dy3+ was prepared by a microwave method.The effect of microwave parameters on the performance of the luminous powder was investigated.The excitation and emission spectrum of the luminous material were measured by fluorospectrophotometer.The phase composition of the powder was analyzed by XRD.The results show that the luminous powder can be synthesized only when the microwave power is higher than the med-high fire (640W).The sample has the best luminous property when the molar ratio of Sr(NO3)2:Al(NO3)3·9H2O:H3BO3:Eu(NO3)3·6H2O:Dy(NO3)3·6H2O is about 1:2:0.5:0.04:0.08,and it is processed by high power for 20min in microwave oven.
