Effect of halogen substitution on the absorption and emission profile of organometallic perovskites

Comparative study on the optical properties of methylamide lead mono- and hybrid-halide perovskite samples, from the perspective of its crystal structure, which were synthesized in ambient condition (temperature ∼26.6 °C, humidity ∼65%), a step toward industrial commercialization, were carried out....
