摘　　要：为探究新型闪烁体材料,选取结构稳定的MB_(2)Si_(2)O_(8)(M=Sr、Ba)为基质,通过比较Pr^(3+)和Ce^(3+)掺杂MB_(2)Si_(2)O_(8)(M=Sr、Ba)样品的真空紫外-紫外(VUV-UV)激发和发射光谱,确定了从Pr^(3+)到Ce^(3+)的能量传递,该体系具有作为闪烁体材料的潜在价值。In order to explore the new scintillator material,the energy transfer from Pr^(3+)to Ce^(3+)is determined by comparing the vacuum ultraviolet-ultraviolet(VUV-UV)excitation and emission spectra of Pr^(3+)and Ce^(3+)-doped MB_(2)Si_(2)O_(8)(M=Sr,Ba)samples with stable structure as the matrix,and the system has potential value as a scintillator material.

关 键 词：硅酸盐 Pr^(3+) Ce^(3+) 闪烁体
