摘要:Dy:Lu2O3 was grown by the float-zone (Fz) method. According to the absorption spectrum, the Judd-Ofelt (JO) parameters Omega(2), Omega(4), and Omega(6) were calculated to be 4.86 x 10(-20) cm(2), 2.02 x 10(-20) cm(2), and 1.76 x 10(-20) cm(2), respectively. The emission cross-section at 574 nm corresponding to the F-4(9/2)-> H-6(13/2) transition was calculated to be 0.53 x 10(-20) cm(2). The yellow F (F-4(9/2)-> H-6(13/2) transition) to blue (F-4(9/2)-> H-6(15/2) transition) intensity ratio ranges up to 12.9. The fluorescence lifetime of the F-4(9/2) energy level was measured to be 112.1 mu s. These results reveal that Dy:Lu2O3 is a promising material for use in yellow lasers.
