摘　　要：目的开发新型多模激励材料LiGaSiO_(4):Mn^(2+),Yb^(3+),分析其光致发光、热致发光及光激励发光特性,为开发多模动态光信息存储及读出提出新思路。方法通过高温固相法制备样品,用光谱仪表征其光致发光性能,用热释光测试其陷阱分布及热致发光性能,用激光器与光谱仪测试光激励发光性能等。结果通过在LiGaSiO_(4)中掺杂Mn^(2+)和Yb^(3+),显示出优异的热致发光及光激励发光特性。结论成功制备出新型绿色长余辉发光材料LiGaSiO_(4):Mn^(2+),Yb^(3+),共掺引入缺陷增强发光性能,实现光信息多模动态读出。Purposes—To develop new multi-modal excitation materials,LiGaSiO 4:Mn^(2+),Yb^(3+)analyze their photoluminescence,thermoluminescence and photoluminescence characteristics,and finally provide new train of thought for the development of multimodal dynamic optical information storage and readout.Methods—The samples were prepared with high temperature solid phase method,and their photoluminescence properties were characterized by spectrophotometer,their trap distribution and thermoluminescence properties were measured by thermoluminescence,and their photoluminescence properties were measured by laser and spectrophotometer.Results—With Mn^(2+)and Yb^(3+)doped in LiGaSiO 4,it shows excellent thermoluminescence and photoluminescence properties.Conclusions—A new type of green long afterglow luminescent material LiGaSiO 4:Mn^(2+),Yb^(3+)has been successfully prepared,and the co-doped defects have been introduced to enhance the luminous performance,thus realizing multimode dynamic readout of optical information.
