采用常规的熔体淬冷法制备了SiO2-B2 O3-Al 2 O3-ZnO-AlF 3-Na 2 O-PbO-Se硼硅酸盐玻璃，并对其进行了PbSe量子点掺杂。我们观察到了宽的近红外（NIR）发射带（960-1353 nm），半峰全宽（FWHM）值为168-294 nm，以及显着的斯托克斯位移（139-167 nm），这取决于温度和热处理的持续时间。在室温下，量子点的光致发光（PL）寿命约为1.24-1.92 μs，并表现出明显的尺寸和浓度依赖性。PbSe量子点掺杂硼硅酸盐玻璃的大半高宽和强近红外发射可以促进其在近红外光放大器和激光器中的应用。
PbSe quantum dots (QDs) were used to dope borosilicate glass with a composition of SiO2-B2O3-Al2O3-ZnO-AlF3-Na2O-PbO-Se, which was prepared using the conventional melt-quenching technique followed by heat treatment. We observed a broad near infrared (NIR) emission (960–1353 nm) band with a full-width-at-half-maximum (FWHM) value of 168–294 nm and a notable Stokes shift (139–167 nm), which depended on the temperature and duration of the heat treatment. At room temperature, the photoluminescence (PL) lifetime was approximately 1.24–1.92 μs, and it showed a clear dependence on the size and concentration of the QDs. The large FWHM and strong NIR emission of the PbSe QD-doped borosilicate glass may facilitate its application in NIR optical amplifiers and lasers.
