Preparation and processing of nanocomposites of all-inorganic lead halide perovskite nanocrystals

subject

description

Abstract Solution processed all-inorganic trihalide perovskite nanocrystals are potential materials for the fabrication of future generation optoelectronic devices. However, the surface of the perovskite nanocrystals should be encapsulated to prevent degradation. Because of their stability under ambient conditions, nanocomposites of perovskite nanocrystals have been intensively researched for display applications. Perovskite nanocrystals dispersion or growth in a polymer matrix imparts structural stability and influences the optical properties, preventing effects such as halide migration. Developing flexible, high-performance lighting devices through perovskite nanocomposites will need to be evaluated on the compatibility of nanocrystals within the polymer matrix. Research in this area has escalated, but specific attention is required to address the practical challenges. This chapter discusses the current developments in the field of preparation and processing of nanocomposites of pure inorganic perovskite nanocrystals. Organic ligands, fabrication methods, encapsulating compounds, solvents, and other deposition procedures affecting the performance and stability of nanocomposites are discussed.
