Investigation of high-performance perovskite nanocrystals for inkjet-printed color conversion layers with superior color purity [PDF]

APL Photonics, 2021
We synthesized cesium lead-halide perovskite colloidal nanocrystals using the hot injection method for wide-color-gamut low-cost displays. An efficient surface defect passivation technique was applied to further improve the optical performance of the green and red perovskite nanocrystals.
