Solution processed hybrid organic-inorganic halide perovskite materials have drawn huge attention in recent years. It attracts due to their potential application in 4th generation of photovoltaic solar cells, light emitting diodes, photo-detectors, laser and related optoelectronic devices. Most commonly, methylammonium lead halide perovskite [CH3NH3PbX3, X = Cl, Br or I] has chemical formula ABX(3) pattern, where A and B represents two cations of dissimilar sizes while X an anion. In the present work, we have successfully synthesized CH3NH3PbI3 hybrid organic-inorganic halide perovskite materials with low temperature solution cost method. XRD diffraction was employed to elucidate the structure of prepared perovskite and the crystalline size also estimated from the full width at half maximum (FWHM). The sharper and more symmetric XRD peaks of perovskite sample indicate a better crystallinity of grains with fewer defects. UV-Visible spectroscopy shows the high absorbance in perovskite between wavelengths 400-800nm. Typical sharp PL peak centered at approximate to 790nm, corresponding to the excitation wavelength of 410nm. We predict that this study will encourage the research on novel near-infrared perovskite materials for optical devices.
