采用高温熔融法制备了一系列Sm3+离子掺杂氟氧化物钙硼硅酸盐玻璃。利用光致发光光谱和衰减曲线对玻璃样品进行了表征。在紫外光激发下，Sm3+离子掺杂氟氧化物钙硼硅酸盐玻璃的发射光谱中观察到红橙子发光。结果表明，其衰减曲线符合单指数衰减规律。此外，通过改变玻璃基质中CaF2的含量，可以实现不同的色度参数和发光寿命，这使得这些玻璃成为发光二极管（LED）的良好候选材料。
A series of Sm3+ions doped oxyfuloride calcium borosilicate glasses were prepared by high temperature melting method. The glass samples were characterized by photoluminescence spectra and decay curves. The reddish orange emitting was observed in the emission spectra of Sm3+ions doped oxyfuloride calcium borosilicate glasses excited by ultraviolet light. It was found that the decay curves followed the single-exponential decay. Furthermore, the chromaticity parameters and luminescent lifetime could be realized by varying the content of CaF2in the glass matrix, which makes these glasses good candidates for light emitting diodes (LEDs).
