  Future generations of liquid scintillator neutrino experiments will require
stably loading tons of candidate isotopes into kiloton-scale detectors,
representing a significant chemical challenge. Nanoparticles containing the
candidate isotopes provide a promising method for this loading. Additionally,
the unique optical properties of nanoparticles can enhance detection and
background discrimination. Perovskite nanocrystals are particularly attractive
due to the reliability of their crystal structure and their easily-scalable
synthesis. We present here the first study of lead-based perovskite
nanocrystals for this application.
