WebMetal halide double perovskites (DPs) are being explored as stable and non-toxic alternatives of Pb-halide perovskites. Typically DPs exhibit a wide (>2.5 eV) and/or indirect bandgap, limiting their applications in the visible … WebMay 8, 2024 · In this study, we report the first example of doping Yb ions into lead-free double perovskite Cs 6 (X = Cl -, Br - 3+ endows the double perovskite NCs with a newly emerged near-infrared emission band (sensitized from the NC hosts) in addition to their intrinsic trap-related visible photoluminescence. By controlling the Yb-doping …

WebMar 7, 2024 · Lead-free perovskite nanocrystals (NCs) were obtained mainly by substituting a Pb 2+ cation with a divalent cation or substituting three Pb 2+ cations with two trivalent cations. The substitution of two Pb 2+ cations with one monovalent Ag + and one trivalent Bi 3+ cations was used to synthesize Cs 2 AgBiX 6 (X=Cl, Br, I) double perovskite NCs. … WebApr 22, 2024 · Under 370 nm excitation (from Xenon lamp with monochromator), the double perovskite film deposited on glass substrate exhibit strong photoluminescence (PL) (Figure 2a inset), confirming the high quality of the vapor‐deposited Cs 2 AgBiCl 6 film, with an emission peak at 600 nm (Figure 2).
