Zinc sulfide crystals grow readily from the vapor phase if small traces of certain impurities, such as zinc oxide and copper, are present. The decrease of ambient impurity concentration leads first to very thin, flexible, ribbon-like crystals which are hexagonal, and finally to nucleation with little growth. The purity of crystals depends not only on the composition of the starting material but also on the purity of the combustion tube employed: contamination during growth leads to an impurity gradient in crystals and to impurity variations among crystals. Crystals usually exhibit disorder of the crystal structure, although pure cubic or hexagonul structure can be achieved by annealing or quenching. Heat treatment also changes the impurity content and attendant propenties, such as physical color, luminescence behavior, electrical properties, and disorder of the crystal structure. (auth)
