摘要：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.
