“…ese peaks denote the organic substances in the associated dye molecules [24]. e pure K 2 SO 4 single crystal emanates the peak at 231 nm which is characterized by the transfer of electrons from a lower energy state to a higher energy state in the UV region [25]. e incorporation of dye into the pure crystal modified the electronic configuration of the K 2 SO 4 crystal.…”

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.

“…e endothermic process of K 2 SO 4 begins at ambient temperature and is completed at 100 °C [27]. Hence, the accumulated dye-doped K 2 SO 4 single crystal is a better thermodynamically stable material, which is suitable for laser and NLO applications [15,[22][23][24][25][26][27][28].…”
