采用水热法在温和的实验条件下制备了GdNbO4:Yb3+/Er3+/Tm3+上转换白光荧光粉.探究了煅烧温度对样品结构和发光性能的影响,并确定了GdNbO4:Yb3+/Er3+/Tm3+荧光粉的较优煅烧温度.研究了不同稀土离子掺杂浓度对GdNbO4:Yb3+/Er3+/Tm3+荧光粉发光性能的影响,并通过控制稀土离子掺杂浓度实现了对荧光粉发光颜色的调节.
Synthesis and luminescence mechanism of rare earth doped gadolinium niobate for white light up-conversion luminescent materials
GdNbO4:Yb3+/Er3+/Tm3+up-conversion white light phosphor was synthesized by hydrothermal method under mild experimental conditions.The effect of different calcination temperatures on the structure and luminescent properties of the samples was evaluated,confirming the optimal calcination temperature for GdNbO4:Yb3+/Er3+/Tm3+phosphor.The influence of doping concentrations of different rare earth ions on the luminescent performance of GdNbO4:Yb3+/Er3+/Tm3+phosphors was investigated,and the luminescent color adjustability of phosphors was achieved by controlling doping concentration.
