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 3.5×10-22 cm2, and the full width at half maximum was found to be 2.85 nm. The Judd-Ofelt (J-O) intensity parameters Ω2, Ω4, and Ω6 were computed to be 3.79×10-20 cm2, 1.30×10-20 cm2, and 1.08×10-20 cm2, with a spectroscopic quality factor Ω4/Ω6 being 1.20. The emission cross-sections of green emission around 543 nm and yellow emission around 584 nm were calculated to be 9.43×10-22 cm2 and 1.32×10-22 cm2, respectively. The fluorescence lifetime τexp of 5D4 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.
