Lead-free europium and ytterbium perovskites

Abstract

perovskites, the iodide-based variant is suitable for device operation within the temperature range of 400 K to 600 K. The bromide-based perovskite is appropriate for temperatures ranging from 500 K to 700 K. In comparison, the chloride-based perovskite can be used for device operation in the higher temperature range of 800 K to 1100 K. Additionally, this research identifies the dynamic stability issue of lanthanide cations in halide perovskites, providing a reference for future lead-free perovskite applications.
