چکیده انگلیسی
In this paper, crack-free and transparent Gd0.9La0.1VO4 single-crystal co-doped with Yb3+ and Ho3+ ions has been grown by Czochralski method. The absorption and emission spectra of the crystal were measured at room temperature. With the absorption spectrum, the intensity parameters Ωλ of Ho3+ ions were fitted based on Judd-Ofelt theory, which are Ω2=7.87Ã10-20cm2, Ω4=7.41Ã10-20cm2 and Ω6=1.99Ã10-20cm2. The spectral parameters of Ho3+ ions were also calculated. The emission spectrum of Gd0.9La0.1VO4 crystal co-doped with Yb3+ and Ho3+ ions was detected when the sample was excited by LD at 980 nm and the intense up-conversion emissions were observed at 550, 660 and 750 nm.
