Abstract The perovskite nanoparticles got much attention in research due to their interesting optoelectronic properties. The true potential application of lead-based perovskite nanoparticle has been hampered due to its toxicity and stability. This paper demonstrated a green approach for toxicity removal of lead halide perovskites to resolve their toxicological aspects using manganese-based metal halide microcrystals. Pb doped Mn-based: CH3NH3Mn1-x PbxBr3-yCly microcrystals show better stability in solid-phase over solution phase with an absolute photoluminescent quantum yield [PLQY] of 30%. All characterization has been done using ultraviolet, photoluminescence, infrared spectra, X-ray photoelectron spectroscopy, X-ray diffraction, transmission electron microscopy, scanning electron microscopy, and thermogravimetric analysis.
