Method for preparing silica-coated perovskite nanoparticles and method for preparing and patterning thin films of the nanoparticles

摘要

The present invention relates to a method for manufacturing silica-coated perovskite nanoparticles, a method for manufacturing a thin film using the prepared perovskite nanoparticles, and a method for forming a pattern of the thin film. Specifically, the present invention provides a method for preparing perovskite nanoparticles with improved properties such as stability by introducing a silica-based precursor during the synthesis of perovskite nanoparticles and coating them with a silica-based material, the prepared nanoparticles A method of manufacturing a thin film through a solution process, and a method of forming a pattern by patterning the thin film by photolithography.
