新型低密度短寿命铈单掺硼硅酸盐玻璃闪烁材料
A Low-density Ce-singly Doped Borosilicate Glass for Novel Short Lifetime Scintillating Material
摘要
Abstract
Borosilicate glass possess natural advantage using as a scintillating material for detection field.To en-rich the application requirements,the Ce3+ ions doped borosilicate glass scintillation material 60B2O3-6SiO2-3Al2O3-5BaO-15Na2O-10La2O3-1Sb2O3 was prepared.The structure was discussed based on density and FT-IR spectra indi-cating that the Ce3+ ions exist as network modifiers.The ultraviolet(UV)absorption boundary was lower than 400 nm and the optical band gap was shorted to 2.93 eV.All these factors are conducive to the luminescent properties of Ce3+ ions.The best emission spectrum was obtained at 372 nm with a 306 nm pumping.The optical basicity was in-creased with the concentration of Ce3+ ions(0.539 2-0.541 7),which resulted in a light red shift of emission spec-tra.The fluorescence lifetime was as short as 24.39 ns,which shows obvious advantages compared with other Ce3+ ions doped scintillation glass.These results provided a new material choice for the development of the detection field.关键词
