Perovskite Nanocrystals

Colloidal synthesis of metal-halide Perovskite nanocrystals, specifically those composed of lead halides. These materials exhibit remarkable properties, with efficient radiative recombination, setting them apart from traditional semiconducting colloidal systems. We study what makes this materials system different. We have successfully developed constantly modifying the colloidal synthesis of two-dimensional CsPbBr3 nanoplates and nanowires. By engineering structures with strong quantum confined excitonic and dielectric effects we can tune the emitted spectrum in nanoplates and polarized emission in nanowires. The vision is to understand and control light-matter interactions for single photon emission and detection.
