Specifically, the present invention relates to a method for the synthesis of metal halide perovskite (CsPbBr3) nano/microcrystals. The present invention uses an easy, scalable low temperature growth of metal halide nanoparticles like CsPbBr3. The method uses a clever play on the solubility and ion exchange mechanism to precipitate nano and microcrystals of metal halide perovskites. The synthesis resulted in stable perovskite crystals with high photo- luminescence, ultralow dark current and control over their morphology. The combination of ultralow dark current, high responsivity, exceptional detectivity, and broad-band photon detection capabilities makes these crystals an excellent choice for upcoming sensors and detector technologies.

In aspects, the conversion of limiting reactants in the synthesis of asymmetrical sulfides unexpectedly remain high under increased flow rates through the catalyst bed, and under reduced temperatures and pressures. In further aspects, reactor systems configured for the independent synthesis of mercaptans and asymmetrical sulfides in a single fixed bed catalyst vessel are also disclosed as a simplification of existing reactor systems employing separate reactors for separate mercaptan and sulfide syntheses.
