Abstract

Objectives: To calculate the optical and structural parameters of the copper sodium tartrate (CuNaT) crystal for investigating its usefulness in the non-linear optics, it was analyzed by XRD and optical studies. Methods : A good nonlinear optical CuNaT crystal was grown by silica gel medium. The fundamental factors to prepare the silica gel for the controlled and defect - free growth of the CuNaT crystal are gel pH, gel density and gel setting period. Findings:The non-centro symmetric structure with refined lattice parameters: a = 7.7230 Å, b = 20.2964 Å, c = 7.9896 Å and the required functional groups: O-H, M-O,C-O and C=O bonds of CuNaT were recognized by the XRD and FTIR studies. Novelty: The monoclinic structure and space group P21 of grown CuNaT crystal was non-identical to the orthorhombic structure of the copper tartrate crystal was enabled to identify its novel structure. The NLO competence of the CuNaT was 0.38 times relative to KDP and of higher LDT value than the KDP, provided its novel optical properties. Applications: The strong intensity emission peaks recorded at 297 nm and 380 nm in the photoluminescence spectrum and the lower absorption edge at 334 nm in the UV spectrum of the CuNaT crystal exhibited its potential use in non-linear optics. Keywords: Single crystal XRD; FTIR; UVVisNIR; PL; SHG; LDT

Summary

Introduction

Organometallic materials have a great impact on information technology and nonlinear optical applications(1). The metal organic polymers or coordination polymers as non-linear optical materials are that molecular architectures can be modulated to optimize the microscopic factors, such as polarization, ionic conductivity, and the related macroscopic parameters such as electrical conductivity (2) and antimicrobial activity (3).Consideration of these properties, nowadays coordination polymers with an excellent optical non-linearity have been the focus on current research activity by knowing their potential applications in optical and biological fields. To accomplish this criterion, tartaric acid derived metal complexes are chosen with their. While we find an adequate literature survey on optical, thermal and dielectric (12) in mixture of metal tartrates using gel technique, there is very less information about the linear and non-linear characteristic properties of copper sodium tartrate, and this present paper intends to account its optical properties for finding applications in non- linear optical fields
