| 摘 要： | 采用溶胶-凝胶法合成了YNbO4∶Tb^3+,Sm^3+系列荧光粉。光谱测试表明:体系中的NbO43-基团能够吸收紫外光并将能量传递给Tb^3+和Sm^3+,从而增强荧光粉的发光强度。在290 nm激发下,YNbO4∶Tb^3+,Sm^3+荧光粉的发射光谱中既出现了Tb^3+的绿光发射又出现了Sm^3+的橙光发射。通过改变Sm^3+的掺杂浓度,实现了荧光粉发射光的光色可调。

| Abstract: | A series of YNbO4∶Tb^3+,Sm^3+phosphors were synthesized by sol?gel process.Photoluminescence spectra show that NbO43-group can absorb ultraviolet light and transfer energy to Tb^3+and Sm^3+,then enhance the luminescence intensity of the phosphor.Under the excitation of 290 nm,characteristic green emission of Tb^3+and orange red emission of Sm^3+were presented in the emission spectrum of YNbO4∶Tb^3+,Sm^3+phosphors.Therefore,the emitting color can be adjusted by changing the doping concentration of Sm^3+. |
