Abstract Scope Since divalent transition metal-doped II-VI compounds were demonstrated as a viable mid-infrared laser material, a significant amount of research energy has been devoted to developing Zn-based optical materials for these applications. Researchers have attempted to synthesize ZnS and ZnSe particles using wet chemistry methods, followed by consolidation via pressing, which is a widely used and cost-effective method to process optical ceramics. In our research work, zinc chalcogenides optical materials were synthesized by a liquid-phase co-precipitation method. The synthesized powders were sintered into optical ceramics, and the XRD analysis and SEM were used to characterize the powder and bulk materials. Meanwhile, the single-crystal flakes of zinc chalcogenides were also used as the starting materials for processing the bulk optical materials through the ceramization of single crystals. The microstructures and optical properties of the optical materials were characterized.
