Optical and microhardness studies on unidirectional grown triaqua glycine sulfato zinc (II): A semiorganic NLO crystal

▶ Triaqua glycine sulfato zinc (II) has been grown by unidirectional crystal growth method. ▶ Enhanced size of 76mm length and 12mm diameter crystal has been grown in a period of 22 days. ▶ The second harmonic efficiency was found to be 2.1 times that of KDP crystal. ▶ The mechanical strength of the crystal has been discussed in detail. ▶ Characterizations such as XRD, FTIR and optical transmission studies are discussed.
