钨酸钆镉晶体的光学性能
OPTICAL PROPERTIES OF CADMIUM GADOLINIUM TUNGSTATE CRYSTAL
摘要
Abstract
The transmittance spectra and the reflection spectra of cadmium gadolinium tungstate [CdGd_2(WO_4)_4,CGW] single crystal were measured in a wave range from 200 to 700 nm. These spectra were treated by mathematical method. The results show that the CGW single crystal has excellent transmittance in the visible range. The absorption coefficient and the extinction coefficient as well as the refractive index of the CGW single crystal in the visible range were determined. A plot of (aE)~(1/2) versus E is used to determine the optical energy gap of the CGW single crystal, and its optical energy gap is about 3.53 eV. This confirms that the CGW single crystal is an indirect gap semiconductor material.关键词
