A series of Tm3+ mono-doped and Tm3+-Eu3+ co-doped transparent glass-ceramics (GCs) containing NaY(MoO4)2 crystal phase was synthesized by melt quenching and glass crystallization. The optimal heat treatment condition, crystal structure, microscopic morphology, transmittance, luminescent properties and energy transfer of samples were studied using DSC, XRD, SEM, spectrophotometer and fluorescence spectrometer, respectively. When the Tm3+ mono-doped concentration is 0.4%, the emission intensity is the strongest at 456 nm due to 1D23F4 transition of Tm3+. Energy transfer from Tm3+ to Eu3+ is observed by fluorescence spectra of Tm3+-Eu3+ co-doped GCs, and the optimal doping concentrations of Tm3+ and Eu3+ are 0.4% and 1.3%, respectively. In addition, the Tm3+-Eu3+ co-doped GCs can achieve tunable emission from blue to purple by adjusting the doping concentration of Eu3+. These results indicate that Tm3+ mono-doped and Tm3+-Eu3+ co-doped GCs have potential applications in the field of color display.

含NaY(MoO 42的Tm 3+和Tm 3+ -Eu 3+掺杂玻璃陶瓷的制备,发光性能和能量转移

通过熔融淬火和玻璃结晶,合成了一系列含有NaY(MoO 42晶相的Tm 3+单掺杂和Tm 3+ -Eu 3+共掺杂透明玻璃陶瓷(GC)。分别用DSC,XRD,SEM,分光光度计和荧光光谱仪研究了样品的最佳热处理条件,晶体结构,微观形貌,透射率,发光性能和能量转移。当Tm 3+单掺杂浓度为0.4%时,由于Tm 3+的1 D 23 F 4跃迁,发射强度在456 nm处最强。。为Tm能量传递3+与Eu 3+由Tm为荧光光谱观察到3+ -Eu 3+共掺杂的GC和Tm的最佳掺杂浓度3+及Eu 3+是0.4%和1.3%之间。另外,通过调节Eu 3+的掺杂浓度,Tm 3+ -Eu 3+共掺杂GC可以实现从蓝色到紫色的可调发射。这些结果表明,Tm 3+单掺杂和Tm 3+ -Eu 3+共掺杂GC在彩色显示领域具有潜在的应用。
