Single crystals of chlorine doped zinc cadmium thiocyanate (ZCTC:Cl) have bee n grown from the mixed solution of KCl and H 2O with the evaporation method at 40 degree.The content of the dopants in the crystal has been determined and chan ges of crystal properties due to the dopants are described.Comparision of the pr operties between the doped ZCTC single crystal and the crystals grown from other solution is given.It is found that ZCTC single crystal doped with suitable amou nt of Cl has some better properties than the ZCTC crystals grown from other solu tion.Reasonable explanation has also been given.
