Figure 1. Structural and spectroscopic characterization of Bi/Ln:Cs2AgInCl6 DPs

Caption

a, XRD patterns of Bi/Ln:Cs2AgInCl6 DPs. b, Energy transfer mechanisms and emission processes involving both STE recombination and Ln3+ 4f-4f transitions. c, PLQYs of the Yb, Nd, Er or Tm single-doped samples, Yb/Nd/Er/Tm multi-doped samples and DiG composite. The insets are Bi/Er-doped sample sintered at 425 °C and 600 °C, respectively. d, Simplified schematic illustration of the heterogeneous architecture (DPs-in-glass). e, PL spectrum of the constructed Bi/Ln:DP-based LED. Inset: Photographs of LED device with an operating current of 200 mA taken by a visible light camera and NIR camera.
