制备了在GeGaSe体系中掺杂Dy~（3+）的硫系玻璃，测定了玻璃样品的密度、显微硬度、可见光红外透射光谱、发射光谱和荧光寿命等性能。根据得到的密度数据计算出玻璃的摩尔体积和紧度。讨论了玻璃的性质随平均配位数r的变化规律。结果表明，当r > 2.67时，该材料在1.3 μm处具有良好的荧光性能，发射寿命为440 ~ 530 μs。在化学阈值的玻璃中发现最强的辐射
Dy~(3+)-doped chalcogenide glasses in GeGaSe system were prepared and the properties of glasses samples including density, microhardness, visilbleinfrared 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 r were discussed. Results show that good fluorescent properties are obtained at 1.3 μm when r 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
