摘要：实验制备了Dy3+掺杂GeGaSe系统硫系玻璃样品,测试了玻璃的密度、显微硬度、可见红外透射光谱、荧光光谱以及荧光寿命。根据玻璃的密度计算了玻璃的摩尔体积以及致密度。讨论了玻璃的这些性能随系统平均配位数的变化关系。实验结果表明:该系统中配位数大于2.67的玻璃在1.3μm具有较好的发光性能,荧光寿命在440～530μs之间,当玻璃组成位于化学门槛即平均配位数为2.73时玻璃的发光强度最强。
Dy3+-doped chalcogenide glasses in Ge-Ga-Se system were prepared and the properties of glasses samples including density, microhardness, visible-infrared transmission spectra, emission spectra and fluorescence life were measured. The molar volume and compactness of glasses were calculated from the density data obtained. The properties of glasses as a function of the average coordination number were discussed. Results show that good fluorescent properties are obtained at 1.3 μm when is greater than 2.67 and the measured emission lifetime is from 440 μs to 530 μs. The strongest emission is found in the glass at the chemical threshold of = 2.73.
