In this paper, X-ray diffraction, selective area electron diffraction, and transmission electron microscope (TEM) were used to study the twins at different positions and textures in different direction in CVDZnS. It was found that the CVDZnS twin showed streaks under TEM. The narrower the streaks, the higher the content of twins, and the content of twins in CVDZnS normal layer was higher than that in bright layer. There are textures in CVDZnS, and the main texture of P surface (perpendicular to the direction of growth) is different from S surface (parallel to the growth direction of surface). The main texture in P is {010} 〈001〉, and the S is {101} 〈 131〉.

ZnS‐reinforced ZnS/ZnSe composites are prepared by chemical vapor deposition. Scanning electron microscope, transmittance, and bending strength are used to characterize the samples. The schematic diagram of the transmittance model of the double‐layer composite window is used to calculate the theoretical transmittance, and the measured value of the transmittance of ZnS/ZnSe composite material is in good agreement with the calculated value. The effects of interface layer on the optical and mechanical properties of materials are studied in detail. It is found that the interface can affect the transmittance of the composites, but it still maintains a high transmittance, and the influence of interface layer on the transmittance of visible band is more serious than that of infrared band. Moreover, the mechanical properties of the new composite material are significantly improved (35%).
