In situ preparation of highly luminescent Sb3+/Mn2+ co-doped Cs2KInCl6 lead-free double perovskite in PVDF matrix and application to white light emitting diode and anti-counterfeiting

Recently, lead-free double perovskites have been regarded as a promising alternative to lead halide perovskite due to its wide emission band, environmental protection and stability, and is expected to become...
