- Abstract
- This paper reports a comparative study of thermal stability between all-organic metal halide perovskite (MHP) CsPbBr3 and organic-inorganic hybrid MHP (methylammonium lead bromide MAPbBr(3)). The film morphology, crystal structure, steady-state photoluminescence intensity, and photoluminescence lifetime of CsPbBr3 and MAPbBr(3) polycrystalline films were measured after thermal annealing at temperatures from 70 degrees C to 230 degrees C. The CsPbBr3 films exhibited little change in their structural and luminescent properties after being annealed even at 230 degrees C, whereas the MAPbBr(3) films exhibited a significant change in such properties due to their decomposition into PbBr2 when annealed at >= 180 degrees C. This study increased the understanding of the difference in the thermal stability of MHP polycrystalline films with different A-site cations.
