Abstract
- High-quality Dy:PbWO 4 crystal has been successfully grown by the Bridgman method. Fluorescence properties of the grown crystal at the yellow-light region were discussed. The absorption cross-section of Dy3+ ions at 454 nm was calculated to be 0.142 × 10−20 cm2, which corresponded to the transition from 6H 15/2 to 4I 15/2 level. Based on Judd-Ofelt theory, the J-O intensity parameters Ω t and the emission cross-section were calculated. The fluorescence lifetime of 4F 9/2 level was measured to be 193 μs. • Dy: PbWO 4 crystal was grown successfully by the Bridgman method. • Judd-Ofelt theory was used to analyze the spectral properties of Dy: PbWO 4 for the first time. • Dy: PbWO 4 crystal is a potential laser medium for yellow laser operation.
