Phase segregation due to ion migration in all-inorganic mixed-halide perovskite nanocrystals
Mixed-halide perovskites possess excellent semiconductor properties but suffer severely from notorious light-induced phase segregation effect. Here Zhang et al. employ simple photoluminescence measurements to link the effect to the local electric field induced ion migration process.
