Abstract

Lead halide perovskite nanocrystals (LHP NCs) featuring tunable band structures and narrow-band emissions are promising candidates for many optoelectronic applications. However, bare LHP NCs undergo rapid decomposition upon exposure to ambient conditions owing to their inherent instability and high sensitivity to external stimuli. In this work, we propose a facile one-step synthesis of stable LHP NCs–geopolymer composites, where Cs LHP NCs are in situ grown and encapsulated in an inorganic framework. This synthetic strategy not only allows the convenient production of Cs LHP NCs with tunable emission for potential display applications but also substantially improves their stability.
