The paper presents the results of TEM and optical transparency measurements on ZnGeP 2 crystals grown by the vertical Bridgman technique from melts of differing compositions. The TEM study reveals the presence of nano-dimensional precipitates of second phases: zinc and Zn xP y precipitation occurs in material grown from Zn-rich melts and GeP from the deficient melts. The precipitation is associated with cooling through the retrograde solidus at a temperature below the melting point. Elastic stress fields are also observed. The relationships between the precipitates and elastic stresses and between precipitation and optical losses are investigated.
