助熔剂对Ca0.7Sr0.3MoO4∶Eu3+红色荧光粉发光性能的影响
Influences of flux on luminescent properties of Ca0.7Sr0.3MoO4∶Eu3+red phosphor
摘要
Abstract
Red phosphors Ca0.7Sr0.3MoO4∶Eu3+were prepared with different fluxes (H3BO3, fluoride fluxes, mixture of H3BO3 and AlF3) by high temperature solid-phase method. The effects of fluxes on phase structure and luminescent properties of phosphors were studied by X-ray diffraction (XRD), excitation and emission spectra. The results show that, the luminescent properties of phosphors are improved by using fluxes except CaF2, and the phase structure of red phosphors is not affected. The best dosage of H3BO3 is 1%of the mass of phosphors. In these fluoride fluxes, AlF3 (dosage is 2%of the mass of phosphors) is the best for improving the luminescent properties of phosphors. H3BO3 and AlF3 added together as flux are better than the flux added independently.关键词
