Realizing efficient photoluminescence spectral modulation via Sb³⁺/Ln³⁺ co-doping in Cs₂NaInCl₆ double perovskites

Abstract

The broad-band self-trapped exciton (STE) emission feature of lead-free halide double perovskites makes it challenging to realize the emission with various wavelengths in a single material. Cs2NaInCl6:Sb3+ crystals with blue...

Band gap engineering and photoluminescence tuning in halide double perovskites

“…Various dopants are employed to achieve efficient broadband emission either through breaking of wavefunction parity or through introducing new luminescence centers in the HDP matrix. 27–36 The effects of common dopants, such as transition metals (TM), rare-earth metals (RE), elements with n s 2 electron configuration and the different combinations of them, are reviewed in this paper.…”
