Abstract

We demonstrate the electron transfer between gold nanoparticles and perovskite CH₃NH₃PbI₃ at a single nanoparticle level by plasmon resonance Rayleigh scattering spectroscopy. Different mass concentrations of CH₃NH₃PbI₃ show different formations of crystal grains on the gold nanoparticles, which led to different degrees of red-shift.
