摘要：采用硫化助熔剂法制备了SrS：Eu，Mn和CaS：Eu，Mn荧光粉。与CaS相比，SrS基质材料的光激励发光峰位于610 nm，比前者更接近视觉敏感区。比较了不同基质材料的存储光和量，SrS基质材料存储能力强于CaS。同时Mn²⁺掺杂增大了碱土金属硫化物被存储的光子数量，有利于提高材料的存储性能。

Abstract：The phosphors SrS：Eu and CaS：Eu doped with Mn were prepared by sulfurization flux method (SFM). Infrared photostimulated luminescence (PSL) of both the phosphors were measured. The PSL peak wavelength of SrS：Eu，Mn is 610 nm. Comparing the storage intensities, SrS has better optical properties. The doping of Mn²⁺ increases photon amount and improves the storage properties.

Key words：Photostimulated luminescence;Mn;Alkaline earth sulphide
