About this Research Topic
Recently, the metal halide perovskite nanocrystals (PNCs) have aroused tremendous research attention due to their excellent photophysical properties, which include high photoluminescence quantum yield, strong light absorption coefficients, compositional dependent bandgap, and narrow emission width. Meanwhile, PNCs’ features have been rapidly developed in technologies such as light-emitting diodes, solar cells, photodetectors, and lasers. However, PNCs exhibit high sensitivity to external conditions, seriously limiting their large-scale application and commercialization. The low formation energy and intrinsic ionic crystal nature of PNCs render them strongly decomposable and unstable upon exposure to oxygen, heat, ultraviolet light, and especially water. Consequently, exploring a convenient and effective method to prepare PNCs with long-term water stability will conspicuously promote the development of PNCs and applications of perovskite-based materials and devices.
Currently, poor stability remains one of the major constraints on the development of PNCs, which not only limits their practical applications but also retards the development of preparation strategies for aqueous-phase synthesis—a green and mild reaction pathway, as a viable method for fabricating conventional colloidal PNCs. With continuous investigation, the introduction of a minor amount of water in the synthesis system can effectively passivate the surface defects and improve the luminescence performance of PNCs. There is a compelling need to develop and refine synthesis approaches that are simple, flexible, affordable, and reproducible, aiming to achieve both high luminescence efficiency and stable dispersion of PNCs to broaden their practical use.
In this Research Topic, we will focus on the investigation of the design and synthesis of PNCs and their applications in various fields such as biology, medicine, and materials science. We particularly encourage manuscripts discussing the strategies or approaches to the stabilization or performance enhancement of PNCs to help advance the investigation of the design and synthesis of PNCs. We are eager to include articles that cover a broad range of topics, including:
• Methods for improving the properties of perovskite nanocrystals for enhanced functionality.
• morphology and size modulation of perovskite nanocrystals
• bio-related detection applications and technical support for the early diagnosis of diseases
