Abstract: Organic-inorganic manganese hybrid halide perovskites have emerged as a promising candidate due to their intriguing features for a variety of optoelectronic applications. The slow evaporation method was utilized to synthesize single crystals of [(CH 3 ) 4 N]MnCl 3 . Powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM) were used to verify the phase's purity and morphology of [(CH 3 ) 4 N]MnCl 3 , respectively. The crystal crystallizes in the hexagonal system with a P 6 3 /m space group. The compound was found to be thermally stable up to a temperature of 400 °C. The direct and indirect optical band gaps were determined to be 2.16 eV and 1.97 eV, respectively. Optoelectronic capabilities of the material were researched as a function of Impedance spectroscopy . At room temperature , it can produce strong red lights at 635 nm with a full width at a maximum of 78 nm when excited by an appropriate UV light source. Ultimately, the material's remarkable photophysical qualities were utilized to accomplish luminescent printing. The permanence of the printed images was confirmed when they showed exceptional clarity even after going through several cycles and stayed visible for a lengthy 15 days in an air environment. With the aid of a UV lamp, the data on the paper can be readily read. These results demonstrate the material's exceptional photoluminescence and optoelectrical capabilities, indicating its potential for exciting applications in optoelectronics, including light-emitting diodes.
