We have reported optical pumped lasing in perovskite semiconducting materials in which we can fabricate thin films with simple solution processes. We fabricated DMF solutions of CH₃NH₃Br or CH(NH₂)₂Br mixed with PbBr₂ in the same molar ratio. The solution was casted on the ITO substrate and capped with another ITO substrate. The cast-capping method can produce good crystals and we can obtain the stable lasing under the pulsed optical pumping. In this presentation, we will report the Electroluminescence properties of the single crystal like films prepared by the cast-capping method.
