Abstract:
GdNbO
4:Yb
3+/Er
3+/Tm
3+ 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 GdNbO
4:Yb
3+/Er
3+/Tm
3+ phosphor. The influence of doping concentrations of different rare earth ions on the luminescent performance of GdNbO
4:Yb
3+/Er
3+/Tm
3+ phosphors was investigated, and the luminescent color adjustability of phosphors was achieved by controlling doping concentration.
