Excitation-dependent perovskite/polymer films for ultraviolet visualization
文献摘要：
Ultraviolet(UV)visualization has extensive applications in military and civil fields such as security mon-itoring,space communication,and wearable equipment for health monitoring in the internet of things(IoT).Due to their remarkable optoelectronic features,perovskite materials are regarded as promising candidates for UV light detecting and imaging.Herein,we report for the first time the excitation-dependent perovskite/polymer films with dynamically tunable fluorescence ranging from green to magenta by changing the UV excitation from 260 to 380 nm.And they still render dynamic multi-color UV light imaging with different polymer matrixes,halogen ratios,and cations of perovskite mate-rials.The mechanism of its fluorescence change is related to the chloride vacancies in perovskite mate-rials.A patterned multi-color ultraviolet visualization pad is also demonstrated for visible conversion of the UV region.This technique may provide a universal strategy for information securities,UV visualiza-tions,and dynamic multi-color displays in the IoT.
