Paper Abstract

High-quality zinc selenide (ZnSe) single crystals were grown by the high-pressure Bridgman method (HPB). Physical vapor transportation (PVT) method was adopted to purify ZnSe (4N) polycrystalline materials. The purity of starting material can be improved to 5N after the purifying process. The effect factors of purifying temperature, oxygen percentage and pressure etc. to the crystal growth were studied. The homogeneity analysis shows that the ZnSe single crystals obtained are highly homogenous and integral. Optical properties analysis shows that the transmittance coefficient of ZnSe single crystal is above 70%, with high refractive index and low absorption coefficient.
