摘要：

Combustion derived Er3+ -doped Y2O3 and Er3+/Yb3+ co-doped Y2O3 powders have been characterized by X-ray diffraction, energy dispersive X-ray analysis, Fourier transform infrared spectroscopy and laser excited spectroscopy. Formation of Y2O3 phosphor was confirmed by X-ray diffraction and energy dispersive X-ray analysis. The vibrational properties of Y2O3 powder was studied by Fourier transform infrared spectroscopy. The luminescence spectra of Er3+ -doped and ER3+/Yb3+ co-doped Y2O3 powders were studied under 379 nm excitation. The strong up-conversion luminescence for Er3+ -doped and Er3+/Yb3+ codoped Y2O3 powders have been observed under 978 nm laser excitation. The effect of Yb3+ addition on optical and luminescence properties of Er3+/Y2O3 powders were studied. The ratio of red to green intensity has been enhanced when Er3+ -doped Y2O3 is co-doped with Yb3+ ions. The effect of co-doping of Yb3+ ions on the visible luminescence intensity of Ei(3+) has been studied and the mechanism responsible for the variation in the green and red intensity is discussed.
