Abstract
- A novel crystal benzophenone's nonlinear optical applications are pivotal. Benzophenone is one of the promising organic nonlinear optics materials for their high energy laser photonic application. It has already been possible to generate crystals of benzophenone in various ways. In this research, the slow evaporation method at room temperature was successful in making a single crystal of benzophenone. In this paper, synthesis, growth, characterization and applications of low melting organic nonlinear optics benzophenone crystal in order to improve their structural and physical properties are reported. Different characterization methods were applied to the grown crystals. The lattice parameters of the grown material were obtained by single crystal X-ray diffraction (XRD) study. The results of the single crystal XRD analysis showed that the produced crystals are a component of an orthorhombic system with the space group P212121 and the lattice parameters are a = 7. 9 9 9 5 (9)  Å, b = 1 0. 2 8 6 5 (1 0)  Å, c = 1 2. 1 2 4 7 (1 3)  Å, α = β = γ = 9 0 ∘ and V = 9 9 7. 7 0 (1 8)  Å<superscript>3</superscript>. Ultraviolet-visible (UV–Vis) spectrum indicates that the crystal is transparent (72%) in the entire visible region with a cutoff wavelength of 258 nm. The transparency of the grown crystals has been confirmed using the UV–Vis spectrum. The second harmonic generation (SHG) efficiency of the grown crystal was measured using an Nd-YAG laser and it was found to be 1.8 greater than potassium dihydrogen orthophosphate (KDP). The FT-IR spectrum was examined in order to identify the many functional groups. The formation of the material was confirmed qualitatively by FT Raman spectral analyses. Mechanical properties such as Vicker's microhardness number, Yield strength, Fracture toughness, Brittleness index and Elastic stiffness constant values were determined using Vicker's microhardness test. The thermal stability of the grown crystal was studied by thermal analysis. [ABSTRACT FROM AUTHOR]
