- 摘要:
- 采用高温固相法合成了系列LaSrZnNbO6:Bi3+,Sm3+荧光粉,并对其发光性质以及Bi3+、Sm3+离子间的能量传递机理进行了研究.结果显示,当以Bi3+的1S0→ 3P1激发位置(338 nm)激发Bi3+和Sm3+共掺杂LaSrZnNbO6荧光粉时,在LaSrZnNbO6荧光粉的发射光谱中同时出现了Bi3+和Sm3+的发射峰,表明在LaSrZnNbO6基质中存在Bi3+→ Sm3+的能量传递.经计算, Bi3+离子和Sm3+离子间的能量传递效率可达到86.9%.通过改变Bi3+离子和Sm3+离子的掺杂浓度可以使LaSrZnNbO6荧光粉的CIE色坐标由蓝光区域移动至粉白光区域,表明通过调节掺杂浓度可制备出颜色可调谐的荧光粉.
- Abstract:
- A series of LaSrZnNbO6:Bi3+/Sm3+/Bi3+,Sm3+ phosphors were synthesized by high temperature solid state reaction method.Their luminescence properties and energy transfer mechanism between Bi3+ and Sm3+ were investigated in this paper.The results show that the emission spectra of Bi3+ and Sm3+ co - doped LaSrZnNbO6 phosphors exhibits both of Bi3+ and Sm3+ emission peaks with excited at the excitation wavelength of 338 nm which is the 1S0→ 3P1 transition of Bi3+.It indicates that Bi3+→ Sm3+ energy transfer exists in LaSrZnNbO6 host.By calculating, the energy transfer efficiency between Bi3+ and Sm3+ ions can reach 86.9%.The CIE coordinates of LaSrZnNbO6 phosphors can be moved from the blue region to the pink - white region by changing the doping concentration of Bi3+ and Sm3+ ions, indicating that color - tunable phosphor can be prepared by adjusting the doping concentration.
