英文摘要	In this study, for the first time, a high-quality 2 at% Dy3+-doped Gd3Sc2Al3O12 (Dy:GSAG) single crystal was grown successfully by the Czochralski method. Spectroscopic properties of the crystal were investigated in detail. The crystal shows an ultra-broad absorption band at around 447 nm with FWHM of 31 nm. The absorption cross-section at 447 nm and emission cross-section at 582 nm are evaluated to be as high as 0.307 x 10(-20) cm(2) and 0.390 x 10(-20) cm(2), respectively. Three intensity parameters omega(t) (t = 2, 4, and 6) as well as spectral parameters were obtained based on the Judd-Ofelt calculation. The fluorescence quantum efficiency eta for the F-4(9/2) level was evaluated to be 77.2%, which was much higher than that of the Dy:YAG crystal. In addition, evident yellow light emitting and white light emission were directly observed in the crystal under 450 nm and 355 nm horizontal and vertical laser excitation, respectively. The results indicate that the Dy:GSAG crystal could be a potential candidate for all-solid-state yellow lasers at 582 nm pumped by a blue InGaN laser-diode.
