Quantum Dot Formation through Controlled Hybrid Perovskite Decomposition within Metal Organic Framework Glass
Developing quantum dots (QDs) with robust and stable photoluminescence are critical for the advancement of optical nanomaterials. However, QD synthesis still usually involves complex nucleation, growth, surface capping, and separation procedures. Herein, we present an approach to generating embedded PbI2 QDs in situ within the matrix of a metal–organic framework (MOF) glass. This is achieved by controllable decomposition of an optoelectronically inactive δ-phase organic lead halide perovskite (OLHP) within the MOF glass, where the high-temperature MOF melt alters the degradation pathway through interfacial bonding and dissolution effects, effectively preventing PbI2 aggregation and passivating the resulting QDs. The resulting composite exhibits high-quality, narrow line width photoluminescence at room temperature, alongside remarkable stability under ambient conditions. This innovative approach offers a sustainable and efficient route for QD generation, underscoring the potential of MOF glass-based composites in optoelectronic applications.
