Abstract In this paper, Dy3+ doped SrCO3–WO3–SiO2 glass ceramics are successfully prepared by melt-quenching method. The microscopic morphology, structure and luminescence properties of Dy3+ doped glass ceramics are investigated through XRD, DSC, SEM, photoluminescence spectra and decay curves etc. It can be determined that the crystalline phase is SrWO4 after comparing with PDF normal card by XRD. Also, combining with the transmission curves, the optimum heat treatment temperature and time are 740 °C/1.5 h. In the emission spectrum, there are three obvious emission peaks at 484 nm, 575 nm and 665 nm, respectively. The optimum concentration of Dy3+ is found to be 1.6 mol, and electric multipole interaction is the main reason for the concentration quenching. The maximum fluorescence lifetime is 796.5 μs.

Dy2O3掺杂SrCO3-WO3-SiO2玻璃陶瓷的发光及制备

摘要 本文采用熔融淬火法成功制备了Dy3+掺杂的SrCO3-WO3-SiO2玻璃陶瓷。通过XRD、DSC、SEM、光致发光光谱和衰变曲线等手段研究了Dy3+掺杂微晶玻璃的微观形貌、结构和发光性能，XRD与PDF标准卡对比确定晶相为SrWO4。此外，结合透射曲线，最佳热处理温度和时间为 740 °C/1.5 h。在发射光谱中，分别在484 nm、575 nm和665 nm处有3个明显的发射峰。发现 Dy3+ 的最佳浓度为 1.6 mol，电多极相互作用是浓度猝灭的主要原因。最大荧光寿命为 796.5 μs。
