Lead-Halide Perovskite Nanocrystals for Light-Emitting Diodes and X-Ray Imaging
This community develops nanoscale lead-halide perovskite materials, primarily cesium lead bromide, to create light-emitting diodes and scintillators for X-ray detection.
The work centers on synthesizing and stabilizing perovskite nanocrystals and quantum dots, with a strong focus on optimizing photoluminescence and quantum yield. Recurring themes include the engineering of ligand chemistry to suppress defects, the development of lead-free alternatives such as copper iodide and manganese halides, and the fabrication of single crystals for detector applications. The research addresses specific challenges in stability, ion migration, and bandgap control to enable efficient red, blue, and near-infrared emission. Applications are concentrated in high-efficiency displays and low-dose medical imaging systems, where material durability and sensitivity are critical.
The community represents 37.3% of all tracked research on caesium, and 2,872 papers here. It also accounts for 6.1% of lead research, with 1,729 papers, and 4.0% of bromine research, with 811 papers.
There are 12,185 papers in this community, publishing most frequently in Advanced Optical Materials, The Journal of Physical Chemistry Letters, and Journal of Materials Chemistry C.
Recent work continues to focus on stabilizing perovskite quantum dots for near-unity quantum yield and developing scintillator films for 3D X-ray imaging. Newer studies also explore copper(I) halide clusters and manganese-doped perovskites as alternatives for dual-color emission and encryption applications.
