为了提高上转换玻璃在蓝绿波段的发光效率,以期望实现蓝绿波段的短波长激光器,以45PbF2+45GeO2+10WO3为基质组份,双掺Yb3+和Er3+稀土离子,采用熔融技术,退火温度为380℃,恒温4 h以上,制得样品。用V-棱镜测得基质折射率为1.517,样品折射率为1.65。同时利用紫外-可见-红外光谱仪在0.35～2.5 μm的波长范围内测试得到样品的透过率,发现基质玻璃在可见与近红外的透过率大于73%,而掺入Er3+/Yb3+的上转换玻璃透过率大于50%,并且有稀土离子的特征吸收峰。用日本生产的Hitachi F-4500荧光光度计,激发波长为980 nm,观测激发光谱,样品在545 nm处有一较强的发光峰,在650 nm处有一个相对弱的发光峰。

To improve the luminescence efficiency of up-conversion glasses in the blue and green wavebands in hope of realizing short wavelenth laser, through the fusion method, the sample based on 45PbF2+45GeO2+10WO3 host glass co-doped with Yb3+/Er3+ rare-earth ions was prepared. During the preparation,glass annealing temperature is 380℃ and maintaining constant-temperature lasts over 4 hours. By using the V-prism, it is found that the refractive index of host glass and the sample are 1.517 and 1.65, respectively. The transmittance is measured by using the ultraviolet-visible-infrared spectrometer in the wavelength range from 0.35 μm to 2.5 μm. The transmittance of the host glass is beyond 73%. That of the sample co-doped with Yb3+/Er3+ rare-earth ions is beyond 50% and there are characteristic absorption peaks of rare-earth ions. The emission spectrum was measured by using Japanese Hitachi F-4500 fluorescent photometer whose pump light is 980 nm semiconductor laser. There are a strong emission peak at 545 nm and a weak peak at 650 nm.
