An organic dye-modified organolead
halide CH<sub>3</sub>NH<sub>3</sub>PbBr<sub>3</sub> nanoparticle (cubic)
is prepared successfully
by using a perylenetetracarboxylic diimide (PDI) bearing an -NH<sub>3</sub><sup>+</sup> headgroup as the capping ligand. The nanopartilces
are homogeneous with high crystallinity. The photoluminescence of
perovskite is quenched completely by the chemically adsorbed PDI molecules.
This efficient fluorescence quenching has confirmed that the PDI molecules
are anchored on the surface of CH<sub>3</sub>NH<sub>3</sub>PbBr<sub>3</sub> nanoparticle. The resulting nanoparticles can be dispersed
in organic solvents, and the resulting dispersion remains stable for
days. This result provides a general guideline for surface engineering
of organolead halide CH<sub>3</sub>NH<sub>3</sub>PbBr<sub>3</sub> nanoparticles.
