摘要 采用微波加热法合成了白光LED用CaWO4∶Eu3+红色荧光粉。利用X射线衍射仪(XRD)对其荧光粉样品的结构进行表征,通过荧光分光光度计研究了其激发、发射光谱。结果表明:所合成的CaWO4∶Eu3+荧光粉样品均为白钨矿结构。合成的一系列荧光粉都可被近紫外光(396nm)有效激发,并且其主发射峰位于617nm处,归属于发光中心Eu3+5D07F2电偶极跃迁,因而发出红色的光;当选择MnO2为微波吸收剂,微波加热时间为20min,功率为590W时,CaWO4∶Eu3+荧光粉样品的发光强度最佳。

Abstract: CaWO4∶Eu3+ red phosphor for white LED was synthesized by microwave heating.The structure of samples were characterized by X-ray diffraction(XRD).The excitation and emission spectra were studied by fluorescence spectrophotometer.The results showed that the samples were scheelite structure.A series of phosphors can be excited by near ultraviolet light (396nm).It was obvious that the main emission peak was located at 617nm and the dipole transition of 5D07F2 belonging to the emission center Eu3+.It was found that the luminescence intensity of samples could be improved effectively.At the same time,the effects of microwave absorber,microwave heating time and heating power,and the effect of different rare earth doped ions on the structure and luminescence properties of phosphor were studied.
