Sr2InP3O11:Eu3+红色荧光粉的发光性能及占位影响
Luminous Performance and Site-occupation Effect of Sr2InP3O11:Eu3+Red Phosphor
摘要
Abstract
Red phosphor is an important component to improve the color rendering index and reduce the color tem-perature of white light emitting diode(LED).In this paper,we select Eu3+with characteristic red emission as activa-tor ions,and new phosphate Sr2InP3O11 is used as the phosphor host.A series of Sr2-xInP3O11:xEu3+(simplified as S2-xIP3:xEu3+)and Sr2In1-xP3O11:x Eu3+(simplified as S2I1-xP3:xEu3+)phosphors were synthesized through high tem-perature solid state reaction.The photoluminescence performance and the effect rule of cation sites(Sr sites and In sites)of phosphor were detailly studied by XRD,room and variable temperature PL spectra,quantum efficiency and fluorescence lifetime.The results show that these two types of phosphors can emit bright red light(dominating by 593 nm and 612 nm)under the radiation of 254 nm and 393 nm.In addition,these synthesized phosphors have aver-age color stability and thermal stability,which indicates that they have certain development potential in the field of phosphor conversion white LED lighting and displaying.关键词
