Résumé

In this work, methylammonium lead halide CH 3 NH 3 PbI 3 (MAPI 3 ) perovskite nanorods were synthesized by the sol gel-spray ultrasonic method. The XRD pattern exhibits peaks assigned to the tetragonal MAPI 3 structure with a residual PbI 2 phase. SEM and AFM images show the formation of nanorods like picture with rough surface. The Raman spectrum was visualized to show various vibration modes in the film. Photoluminescence data revealed one emission peak at 786 nm (1.58 eV) in the band gap band, which was confirmed by the UV-Vis spectrum. The slight difference between the found band gap energy and the ideal one is explained in terms of shallow trap states.
