“…In the spectrum of the dielectric constant, the temperature with the applied frequency gradually increased due to its space charge polarization with the heat and its electric and ionic dipolar nature. e lower frequency produced a higher dielectric constant in a particular temperature than in other temperatures [33] because of their space charge and macroscopic distortion between the charge carriers. At the same time, the high frequency produced the lower dielectric constant at certain temperatures due to their ionic and electronic polarization.…”

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.
