ICMPC 2017 Growth and characterization of L-histidinium perchlorate crystals (LHP) S. Nalini Jayanthi a * , N. Bhuvaneswari a a Department of Physics, KCG College of Technology, Chennai, India Abstract L-histidinium perchlorate, a semi-organic nonlinear optical (NLO) material was synthesized by standard slow evaporation solution growth technique. The single crystals were subjected to various characterizations. Powder XRD and FT-IR spectral analysis were carried out confirm the LHP crystals. The nonlinear optical behavior of the crystal was tested using Kurtz-Perry powder technique. The suitability of the crystal in device fabrication was confirmed by testing its thermal stability. The photoconducting property of the crystal was also studied. © 2017 Elsevier Ltd. All rights reserved.

Introduction The search and design of highly efficient nonlinear optical (NLO) crystals for visible and ultraviolet (UV) regions are extremely important for laser and material processing. Semi-organic NLO crystals formed with L-histidine has been identified as potential candidates for replacing KDP in nonlinear optical applications because they have the combined advantages of both organic and inorganic materials [1]. Amino acids and inorganic acids are good raw material to produce semi-organic crystals [2,3]. In the present investigation, a systematic study has been carried out on the growth of L-histidinium perchlorate (LHP) crystals by slow solvent evaporation technique. The grown crystals were subjected to powder XRD to * Corresponding author. Tel.: +91-988-499-2842 E-mail address:nalinijayanthi80@hotmail.com
