Abstract:
The influence of nanostructured titania surface on the photoluminescence of organometallic perovskite CH3NH3PBI3 films is studied. It is found that the CH3NH3PBI3 luminescence intensity and lifetime decrease on the TiO2 surface, which testifies to charge transfer from perovskite to titania. Charge transfer occurs most efficiently for perovskite films synthesized on the surface of mesoporous TiO2 films. The time dependence of magnetic effect on the luminescence of CH3NH3PBI3 on mesoporous TiO2 films is related to the recombination luminescence caused by forward and backward electron transfer between perovskite and titania.
Keywords:
