摘要：

A series of Li+Bi3+ co-doped Lu2O3, Ho3+ phosphors are prepared by the high temperature solid-state method. The research results show that the doping of Li+, Bi3+ and Ho3+ with different mole fractions does not change the cubic phase structure of Lu2O3. Compared with that of Lu2O3 : 2 % Ho3+ sample, the luminescence intensities of the three kinds of samples doped with 16% Li+, 1. 5%; Bi3+ 2% Li+/1. 5% Bi3+ increase by 3. 0, 128.9, 1.4 times, respectively. However, the fluorescence lifetimes of these three kinds of samples under the excitation of a laser with a wavelength of 449 nm are shortened by different degrees.
