Surface decorating of CH3NH3PbBr3 nanoparticles with chemically adsorbed porphyrin

An organolead halide (CH3NH3PbBr3) nanoparticle was modified successfully with a porphyrin (POR) bearing an -NH3+ head group. The nanoparticles are homogeneous with high crystallinity. The photoluminescence of CH3NH3PbBr3 is quenched completely by the chemically adsorbed POR molecules. The efficient energy transfer from CH3NH3PbBr3 to POR is responsible for the fluorescence quenching. The modified nanoparticles can be dispersed in organic solvents and the resulting dispersion remains stable for several days. This result provides a new way to tune the photophysical properties of organolead halide CH3NH3PbBr3 nanoparticles.
