| 英文摘要 | GdScO3 and Yb:GdScO3 single crystals are grown by the chzochralski method in nitrogen atmosphere, and they are characterized by X-ray diffraction(XRD), Raman spectra and transmission spectra . Their lattice parameters, atomic coordinates and temperature factors are determined by Rietveld refinement. It is found that the cell volume of GdScO3 and Yb:GdScO3 annealed in air atmosphere increase, but after these sample are annealed in H-2 atmosphere their cell volumes decrease. Based on these results, we demonstrate that the crystal grown in nitrogen atmosphere has interstitial oxygen atoms, and the number of interstitial oxygen atoms in the sample annealed in air atmosphere increases, but that annealed in H-2 atmosphere decreases. The Raman peaks of 155 cm(-1), 298 cm(-1), 351 cm(-1) of GdScO3 are weakened or even disappear when Yb3+ ions are doped into it. The Raman spectra of the Yb:GdScO3 unannealed and annealed in H-2 and air atmosphere are nearly consistent with each other, which indicates that Raman spectrum is insensitive to the defects such as oxygen interstitial caused by annealing. It is suggested that the optical loss of GdScO3 in the visible wavelength originates mainly from the defect energy level absorption of oxygen interstitial, and transmissivity of Yb:GdScO3 increases when it is annealed in hydrogen atmosphere, which results from the fact that ytterbium ion can reduce some interstitial oxygen atoms. When GdScO3 and Yb:GdScO3 are annealed in air or hydrogen atmosphere, the optical absorption loss of GdScO3 and Yb:GdScO3 in a wavelength range of 1000-3000 nm increase due to the trap level produced near the conduction or valence band. The effect on structure and spectral properties of Yb:GdScO3 and GdScO3 are explored preliminarily, which is useful for further studying and optimizing laser performance of rare earth doped GdScO3 crystal. |
