Description
Summary:Metal halide perovskites (MHPs) are in a blossoming status where their inherent optoelectronic properties are being revisited from the perspective of both fundamental science and practical application. In an attempt to boost the manipulating photoluminescence performance of MHPs, it is timely and vital to review the relation between structural attributes and the photo-physical phenomena for their unique broad-band emissions. In this review, we highlight the luminescent mechanisms of MHPs from dopants, self-trapped excitons (STEs) and defects, and some progresses with an emphasis on how multi-color broad-band emitters can be designed in various classes of MHPs frameworks. We also summarize the integration of MHPs into optoelectronic devices including light-emitting diodes, X-ray scintillators, fluorescence sensors and thermometers. This review aims to provide an in-depth insights into the structure-luminescence relationships from mechanism, materials, and applications, and further pave a way to discuss the current challenges and future promising prospects in MHPs.
