Abstract

Abstract The metastable zone width and induction period of ZTS solution have been measured to investigate the influence of H3PO4 on solution stability, and it could be improved by adding phosphoric acid. Pure and H3PO4 doped ZTS crystals have been successfully grown using the slow-cooling method in aqueous solution. Several crystal samples were characterized by XRD, FTIR, TG, DTA, DTG, UV-VIS and SHG. The results show that some changes have taken place on external morphology and internal structure after H3PO4-doping. Thermostability, light transmittance and SHG efficiency of ZTS crystals are also affected by H3PO4, and all of them become better than undoped crystal, which are meaningful for practical applications of crystals.
