摘要	Through a co-precipitation method Gd(OH)(3): 0.5% Tm3+, 10% Yb3+ powder was synthesized. After sintering at different temperatures, the as-prepared Gd(OH)(3): 0.5% Tm3+, 10% Yb3+ powder was changed into cubic and monoclinic phase Gd2O3: 0.5% Tm3+, 10% Yb3+ phosphors. Crystalline phases and morphologies of as-prepared powder and phosphors were characterized by X-ray diffraction (XRD) and field emission scanning electron microscope (FE-SEM). Up-conversion (UC) fluorescence spectra of Gd2O3: 0.5% Tm3+, 10% Yb3+ phosphors were recorded by a fluorescence spectrophotometer with a 980 nm continuous wave laser diode as the excitation source. Fluorescence decay behaviors of the phosphors were measured by exciting with 980 nm from an optical parametric oscillator (OPO) pumped by a pulsed Nd: YAG laser with a pulse duration of 10 ns and a repetition frequency of 10 Hz, and the signal was recorded using a monochromator and an oscillograph. Phase and excitation power dependent UC fluorescence properties of the phosphors were studied in detail in the article. Interestingly, the cubic phase phosphors presented thermal optical bistability phenomena. The fluorescence dynamic analysis indicated that rise and decay processes existed in the phosphor UC fluorescence. (C) 2010 Elsevier B.V. All rights reserved.
