Organo-lead mixed halide perovskites have been showing remarkable performance for applications in solar cells and are very promising for numerous applications in optoelectronics and nonlinear optics. In this study, we report a room-temperature photoluminescence study of this material by using pulsed excitation laser sources at 1064 nm wavelength. Under our experimental conditions, strong photoluminescence was observed only for bromine-containing perovskites, CH3NH3Pb(I1−xBrx)3, thus suggesting an important role of bromine for photoluminescence of halide perovskites. The experimental results also showed that the photoluminescence peak was blue-shifted from 727 nm to 574 nm when x increased from 1/3 to 1. In particular, the photoluminescence peak featured a third-order dependence on the laser intensity. This direct observation of three-photon absorption-induced photoluminescence of organo-lead mixed halide perovskite materials thus opens up interesting applications in the field of optoelectronics and nonlinear optics.
