CdS QDs (quantum dots) were precipitated in the Pr3+-doped silicate glass by the melting-quenching method. The crystallization behavior and luminescent property of the Pr3+-doped CdS QDs silicate glass were analyzed by XRD, Raman, TEM, UV–Vis–NIR scanning spectrophotometer and fluorescence spectra. It was found that with the increase in the heat-treatment temperature, the size of CdS particles increased from 2.30[Formula: see text]nm to 3.63[Formula: see text]nm, while red-shift was observed in absorption and fluorescence spectra excited at 370[Formula: see text]nm. Fluorescence measurements of the glass showed that the growth of CdS QDs induced a considerable enhancement in the emission spectra of Pr3+, and the sensitization is due to the energy transfer from CdS QDs to Pr3+ ions.

Pr3+掺杂CdS QDs硅酸盐玻璃的结晶和发光

CdS QD（量子点）在 Pr 中沉淀3+用熔融-淬火法掺杂的硅酸盐玻璃。Pr的结晶行为和发光性质3+通过XRD、Raman、TEM、UV-Vis-NIR扫描分光光度计和荧光光谱分析了掺杂的CdS QDs硅酸盐玻璃。发现随着热处理温度的升高，CdS颗粒的尺寸从2.30[式：见文]nm增加到3.63[式：见文]nm，而吸收光谱和荧光光谱出现红移在 370 [公式：见正文]nm 处激发。玻璃的荧光测量表明，CdS QDs 的生长导致 Pr 的发射光谱显着增强3+，并且敏化是由于从 CdS QDs 到 Pr 的能量转移3+离子。
