摘要：

The crystal growth, x-ray diffraction pattern, absorption spectrum, emission spectrum, and fluorescence lifetime of a Tb:Lu2O3 single crystal were studied. Excited at 483 nm, the peak absorption cross-section was calculated to be 3.5 x 10(-22) cm(2), and the full width at half maximum was found to be 2.85 nm. The Judd-Ofelt (J-O) intensity parameters Omega(2), Omega(4), and Omega(6) were computed to be 3.79 x 10(-20) cm(2), 1.30 x 10(-20) cm(2), and 1.08 x 10(-20) cm(2), with a spectroscopic quality factor Omega(4)/Omega(6) being 1.20. The emission cross-sections of green emission around 543 nm and yellow emission around 584 nm were calculated to be 9.43 x 10(-22) cm(2) and 1.32 x 10(-22) cm(2), respectively. The fluorescence lifetime tau(exp) of D-5(4) was fitted to be 1.13 ms. The data suggest that the Tb:Lu2O3 crystal could be a potential candidate for green and yellow laser operation.
