ZnSe和Cr∶ ZnSe单晶的温梯法制备及光学性能研究
Preparation and Optical Properties of ZnSe and Cr∶ ZnSe Single Crystal Grown by Temperature Gradient Technique
摘要
Abstract
Large sized high quality ZnSe crystal was grown by the temperature gradient technique (TCT) method. The optical property of the as-grown ZnSe crystal was studied. Chromium films were deposited on the surface of ZnSe crystal by magnetron sputtering method, the mid-infrared Cr: ZnSe laser crystals were prepared by the thermal diffusion method. Hie spectral properties of Cr: ZnSe were investigated. The absorption spectra of Cr: ZnSe shows a strong broad absorption band with a peak at about 1800 run is attributed to the 5T2→5E transition of the Cr2+ ( 3d4) substituted for the Zn2+ in the tetrahedral site. PL spectra measured at 77 K of Cr: ZnSe crystal shows broad band emission around centre wavelength at 2.2 μm.关键词
