Synthesis, Growth, and Characterization of Methyl Orange Dye-Doped Potassium Sulphate Single Crystal and Its Multifaceted Activities

Abstract

Methyl orange dye-doped K2SO4 single crystal has been synthesized by a slow evaporation method, and its properties have been investigated. The powder X-ray diffraction (PXRD) studies on the single crystal confirmed the crystalline property, noncentrosymmetric system, and the space group P63/mmc (D64th) of crystal. The reaction involved in the functional group of the grown crystal has been confirmed from the FTIR analysis. The optical properties of absorbance and band gap were calculated from the UV-Vis analysis. The obtained materials were identified from the EDX analysis. The electron transformation and optical distortion were identified at 270 nm in the photoluminescence study. The transmission electron microscopy method analyzed the morphology of the grown crystal. The dielectrics of the grown crystal were studied. The effect of temperature on the grown crystal was studied using the TG/DTA analysis. The bacterial susceptibility of the grown crystal was evaluated from Gram-positive and Gram-negative bacteria. All the results demonstrated that the grown crystal is suitable for optical, electronic, and bacterial applications.

A novel stilbazolium derivative crystals of 4-[2-(4-dimethyl amino-phenyl)-vinyl]-1-methyl-pyridinium+ bromide− (DMSB) single crystal: exploration of the growth, molecular structure, linear optical, and third order nonlinear properties

“…The results from SCXRD studies conrmed that the grown DMSB belonged to the centrosymmetric space group P2 1 /c. The centrosymmetric pattern in the crystal species the presence of inversion symmetry in the structure, which implied the presence of the (c (3) ) effect and the absence of the (c (2) ) effect. The sign and magnitude of the nonlinear refractive index (n 2 ) of the title compound were ascertained by using the closed aperture (CA) mode.…”

“…39,40 Theoretically, m is 1/2 for directly allowed transition, m is 2 for indirectly allowed transition, if the m value is 3, it means that it represents direct forbidden transition and if it is 3/2 means it implies indirect forbidden transition. To estimate the material band gap from Tauc plot, a graph between (ahy) 2 and is plotted (Fig. 11).…”

“…Recently, nonlinear optical (NLO) materials that are capable of converting frequency are of great interest to a lot of researchers across the globe owing to their applications, such as optical memories, optical switches, optical modulation, laser sensing, image processing, photonic devices, telecommunication, and frequency conversion. [1][2][3][4] Therefore, new nonlinear optical materials are required to satisfy the day-to-day technical requirements. 5 Numerous efforts have been made in the past to create a novel organic material having signicant nonlinear properties.…”
