Abstract

We synthesized the gold nanoparticles (Au NPs)-embedded methylammonium lead iodide ($MAPbI_3$) film for the first time. The effects of metal nanoparticles on $MAPbI_3$ perovskite were systematically studied using UV-Vis absorption and photoluminescence (PL) measurements. As a result, the 20-nm-sized Au NPs-embedded $MAPbI_3$ film exhibited a 4.15% higher absorbance than the bare $MAPbI_3$ film. Moreover, the average PL intensity of the Au NPs-embedded $MAPbI_3$ film increased by about 75.25% over the bare $MAPbI_3$ film. Therefore, we have confirmed that addition of the Au NPs has a positive effect on the optical properties of $MAPbI_3$, and we believe that this study will provide a basic insight into the metal nanoparticles-embedded perovskite thin films for the future optoelectronic applications.
