| Abstract: The invention provides a convenient solution-based synthesis for metal
halide perovskite particles. This method requires only mild conditions
and can be easily scaled up. A ligand of a proper molecule size and an
optimized precursor ratio are important to obtain pure phase particles.
As an example, lead bromide perovskite particles exhibited a narrow
monochromatic band gap, which can be tuned by partial halide
substitution, and PLQY up to 75% making this material an excellent
candidate for light emission and display applications. |
