Optical Properties and Microscopic Structures of Heat Isostatic Press(HIP)Processed Chemical Vapor Deposition Zinc Sulphide
CVDZnS热等静压(HIP)前后光学性能和显微结构的研究

The transmittance of CVDZnS before and after heat isostatic processing (HIP)was measured. X-ray diffraction, AEM and metaloscopy were adopted to study the microstructure of stereotype and HIP processed CVDZnS. Based on the different microstructures of CVDZnS before and after HIP observed , the reasons why the transmittance of CVDZnS can be improved after HIP processing was analysised. The results show that the grain size of CVDZnS is improved dramatically after HIP processing , and the defects formed during the growth of CVDZnS are minimized, so the transmittance of CVDZnS is improved for the decrease of scatter losses at the grain boundary and structure defects.
