This article investigates the scientific basis for the development of highly efficient light-emitting coatings based on rare-earth-doped perovskite nanocrystals. The optical properties, photoluminescence efficiency, and stability enhancement of perovskite nanocrystals through rare-earth ion modification are analyzed. Energy transfer mechanisms and potential applications in optoelectronic devices and light-emitting technologies are also discussed.
