Abstract

We synthesized the gold nanoparticles (Au NPs)-embedded methylammonium lead iodide (MAPbI3) film for the first time. The effects of metal nanoparticles on MAPbI3 perovskite were systematically studied using UV-Vis absorption and photoluminescence (PL) measurements. As a result, the 20-nm-sized Au NPs-embedded MAPbI3 film exhibited a 4.15% higher absorbance than the bare MAPbI3 film. Moreover, the average PL intensity of the Au NPs-embedded MAPbI3 film increased by about 75.25% over the bare MAPbI3 film. Therefore, we have confirmed that addition of the Au NPs has a positive effect on the optical properties of MAPbI3, and we believe that this study will provide a basic insight into the metal nanoparticles-embedded perovskite thin films for the future optoelectronic applications.
