Biotoxicity of Halide Perovskites in Mice
Advanced Materials, 2023 AbstractHalide perovskites are crystalline semiconductors with exceptional optoelectronic properties, rapidly developing toward large‐scale applications. Lead (II) (Pb2+) is the core element used to prepare halide perovskites. Pb2+ can displace key 2+ elements, including calcium, zinc and iron, that regulate vital physiological functions.
