| 摘 要： | 采用高温熔融法制备了组分为50SiO_2-xAl_2O_3-(50-x)MgO-Bi_2O_3(x=5,10,15,20,摩尔比)的铋掺杂铝硅酸盐玻璃。研究了铋掺杂铝硅酸盐玻璃超宽带近红外发光性质,探讨了玻璃基质的光学碱度对铋离子宽带发光特性的影响。结果表明:在690nm和808nm的激发下,铋掺杂铝硅酸盐玻璃的红外荧光中心分别位于1106nm和1294nm;随光学碱度的增强,铋离子的红外发光强度减弱。并对铋离子超宽带发光的机理进行了探讨,认为其红外发光源于低价的Bi~+和Bi~(2+)。

| Abstract: | The Bi-doped aluminosilicate glasses with molar composition of 50SiO2-xAl2O3-(50-x)MgO-lBi2O3 (x=5, 10, 15, 20) were prepared by conventional melting-quenching technique. The broadband infrared (IR) luminescence properties of the glasses were studied. IR fluorescence centered at 1106 nm and 1294 nm was observed under 690 and 808 nm excitation, respectively. The influence of optical basicity of the glass host on broadband infrared fluorescence was investigated. The intensity of the IR fluorescence decreased with the increase of the optical basicity of glass host. It is revealed that the IR luminescence is due to low valencestate bismuth ions Bi+ and Bi2+. |
