【摘要】 采用熔融晶化法成功制备了Dy³⁺/Tb³⁺双掺含SrWO4晶相玻璃陶瓷,并对其光学性能进行研究。利用差示扫描量热分析仪（DSC）确定了热处理温度,利用X射线衍射（XRD）确定了玻璃基质中有SrWO₄晶粒析出,并结合透过率曲线确定最佳析晶温度和时间为710℃保温1.5 h。探讨了当Dy₂O₃的浓度为0.8%（n/n）时,Tb₄O₇浓度对玻璃陶瓷样品发光性能的影响,在Dy³⁺/Tb³⁺双掺玻璃陶瓷的发射光谱中表明:在350 nm激发下,544 nm处存在明显的发射峰。随着Tb₄O₇浓度增加,能量传递效率逐渐增加。当Tb₄O₇浓度达到1.9%（n/n）时,绿光发射强度达到最大值。结合Dexter能量传递理论和荧光衰减曲线,确定了Dy³⁺到Tb³⁺存在能量传递。更多还原

【Abstract】 Dy³⁺/Tb³⁺co-doped glass ceramics containing SrWO₄ crystal were synthesized successfully by meltcrystallization method and luminescence properties were studied. The optimum heat treatment temperature and time were determined by differential scanning calorimetry（DSC）, the precipitation of SrWO₄ grains in the precursor glass was determined by X-ray diffraction（XRD） and combining with the transmittance curves, the optimum heat treatment system was determined at 710 ℃ for 1.5 h. When the concentration of Dy₂O₃ was 0.8%（n/n）, the effect of Tb₄O₇ concentration on the luminescence properties of glass ceramic samples were discussed. It could be seen that with the excitation wavelength 350 nm, there was an obvious peak at 544 nm in the emission spectra of Dy³⁺/Tb³⁺co-doped glass ceramics. With the increase of Tb₄O₇ concentration, energy transfer efficiency increased gradually, and when the Tb₄O₇ concentration was 1.9%（n/n）, the luminescence intensity of green light reached maximum.Basing on the energy transfer theory of Dexter and the decay curves, the energy transfer from Dy³⁺to Tb³⁺was determined.更多还原
