摘要: 本文采用高温固相法制备了Sr3B14O24:Cu2+系列荧光粉，通过XRD、紫外–可见漫反射、光致发光光谱等手段系统研究其结构与发光性能。结果表明，Cu2+可成功取代Sr2+进入Sr3B14O24晶格，未破坏基质主相结构；样品在325 nm处存在单一激发峰，归属于O2−-Cu2+电荷转移跃迁，对应584 nm黄色宽发射峰，最佳掺杂量为1.5%。本研究完善了Cu2+发光机理，为Cu2+激活发光材料的设计与应用提供实验参考。
Abstract: In this study, Sr3B14O24:Cu2+ series phosphors were synthesized using a high-temperature solid-state method, and their structural and luminescent properties were investigated using XRD, UV-Vis diffuse reflectance and photoluminescence. The results indicate that Cu2+ can successfully substitute for Sr2+ in the Sr3B14O24 lattice without disrupting the structure of the host phase. The samples exhibit a single excitation peak at 325 nm, attributed to an O2−-Cu2+ charge transfer transition, corresponding to a broad yellow emission peak at 584 nm. The optimal doping level was found to be 1.5%. This study refines the luminescence mechanism of Cu2+ and provides experimental references for the design and application of Cu2+-activated luminescent materials.
