摘要: Organic-inorganic metal halid perovskite is an emerging field of promising semiconductive material in optoelectronic devices applications. It has been a research topic of interest for scientists. To date, photoluminescence (PL) efficiency of perovskite is low and does not have any literature to report the solution. Here, we proposed and demonstrated an effective approach for the improvement of perovskite PL characteristics. The PL intensity and spectra bandwidth could be enhanced significantly by using Al-disk metasurface formed on perovskite surface. Such strategy can be exploited to enhance perovskite PL characteristics for developing high efficient light emitting diodes, solar cells, and photodetectors, etc.
