Abstract
The frequent demand of excellent quality NH4H2PO4 (ADP) crystal is encouraged for photonic device fabrication hence present communication is focused to grow the tartaric acid (TA) influenced NH4H2PO4 (ADP) crystal and investigate the role of TA that enabled remarkable modification in morphology and optical properties of ADP crystal. The TA influenced ADP single crystal has been grown by slow solvent evaporation method at room temperature. The pure and TA influenced ADP crystal samples were subjected to powder X-ray diffraction analysis to confirm the crystalline phase and evaluate the structural parameters of respective crystal. The exceptional transformation in external morphology of ADP crystal due to presence of TA has been systematically evaluated. The frequency doubling phenomenon i.e. second harmonic generation efficiency of pure and TA influenced ADP crystal has been experimentally determined by means of Kurtz-Perry powder test and observed decrease in SHG efficiency of TA influenced ADP crystal has been discussed. The influence of TA on photoluminescence nature of ADP crystal has been investigated within wavelength range of 350-700 nm. (C) 2017 Elsevier GmbH. All rights reserved.
