量子点掺杂玻璃是当前新型光通信材料研究的一个热点。用熔融法成功制备了PbSe量子点钠硼铝硅酸盐玻璃。用X射线衍射仪和透射电镜分析了玻璃中PbSe量子点的结晶、尺寸以及分布情况，并用紫外可见近红外分光光度仪和荧光光谱仪分析了PbSe量子点玻璃的吸收谱和荧光发射谱。结果表明，当热处理温度低于500 ℃时，玻璃没有荧光辐射。当热处理温度高于550 ℃时，随着热处理温度的升高，PbSe量子点尺寸增大、分布密度变小。在1064 nm激光照射下，观测到玻璃有强荧光辐射，其辐射峰的半峰全宽为275~808 nm，峰值波长1676~2757 nm。峰值波长与量子点尺寸密切相关，辐射与吸收峰值波长之间的斯托克斯频移为20~110 nm。

As a novel optical communication material, quantum dot (QD)-doped glass became one of the focal researches in recent years. PbSe QD-doped sodium-aluminum-borosilicate glass is fabricated successfully by the melting method. The crystallization, size and distribution of the PbSe QD in the glass are investigated by X-ray diffractometer and transmission electron microscopy. The absorption and photoluminescence (PL) spectra of the PbSe QD doped-glass are also observed by UV-visible-NIR spectrophotometer and fluorescence spectrometer, respectively. The obtained results suggest that, when heat treatment temperature T is lower than 500 ℃, there is no observed PL emission in glass under irradiation of 1064 nm laser. When treatenent temperature T>550 ℃, the glass appears strong PL emissions with full width at half maximum (FWHM) in the range of 275~808 nm, and the PL peak wavelengths in 1676~2757 nm region strongly depended on the QD size. The size of PbSe QD is positively correlated with the heat treatment temperature, a Stokes shift of between the absorption and PL peaks is 20~110 nm.
