Dy:Lu2O3 was grown by the float-zone (Fz) method. According to the absorption spectrum, the Judd-Ofelt (JO) parameters Ω2, Ω4, and Ω6 were calculated to be 4.86×10-20 cm2, 2.02×10-20 cm2, and 1.76×10-20 cm2, respectively. The emission cross-section at 574 nm corresponding to the 4F9/26H13/2 transition was calculated to be 0.53×10-20 cm2. The yellow (4F9/26H13/2 transition) to blue (4F9/26H15/2 transition) intensity ratio ranges up to 12.9. The fluorescence lifetime of the 4F9/2 energy level was measured to be 112.1 μs. These results reveal that Dy:Lu2O3 is a promising material for use in yellow lasers.
