Abstract
Sodium acid phthalate C8H5NaO4 is one of the suitable semiorganic single crystals hired in second harmonic generation conversion applications. In the present work, optically transparent Benzophenone doped with sodium acid phthalate (SAPB) single crystals were grown successfully by slow evaporation solution technique. Single crystal XRD analyses exposed that the crystal lattice of SAPB crystal is a monoclinic crystal system with unit cell parameters a = 6.77 Å, b = 9.31 Å, c = 13.58 Å, and space group B2cb. The crystalline nature of SAPB material was confirmed by powder XRD pattern. The functional groups present in the grown crystals were identified by the FTIR analysis ranging between 4000 and 500 cm−1. The optical transparency and band gap of grown crystals were measured from UV-Visible spectroscopy. The fluorescence emission spectrum of the SAPB crystal having a strong Yellow emission peak at 574 nm and the red emission at 631 nm are identified. The Vickers microhardness number (Hv) increases with increasing load. Meyer’s index number (n) calculated from Hv shows that the material belongs to the soft material category. Preliminary measurement using Kurtz powder technique with Nd-YAG laser light of wavelength 1064 nm indicates that their second harmonic generation (SHG) efficiencies of the grown crystals were presented 2 times in comparison with Potassium Dihydrogen Phosphate (KDP) was confirmed.
Highlights
Recent interest in research focuses much on the search for highly efficient second order nonlinear optical (NLO) materials due to their potential applications in data storage devices, optical communication, optical switches, optical frequency conversion, laser-based images, optoelectronics, telecommunication [1] [2]
The desired nonlinear optical material must exhibit large second-order optical nonlinearities, Semiorgani NLO crystals have a wide range of applications like high transparency range and the material is sodium acid phthalate (C8H5NaO4) doping of external impurity plays a crucial role in tuning the properties of the host crystal, the most effective strategy to gain improvement in intrinsic properties of SAPB crystal is to incorporate benzophenone (C13H10O) impurities in a selected quantity [3] [4] [5] [6] [7]
