Lattice Doping of Lanthanide Ions in Cs2AgInCl6 Nanocrystals Enabling Tunable Photoluminescence
Structural characterization of Ln3+ ()-doped Cs2AgInCl6 NCs. (a) XRD patterns and (b–e) Rietveld refinements of XRD patterns for undoped and Ln3+-doped Cs2AgInCl6 NCs. (f) The cell volume of Cs2AgIn1-xCl6:xLn versus dopant concentration (, 5%Dy, 12%Sm, 17%Tb). (g–i) TEM images (up), selected area electron diffraction (SAED) patterns (left bottom), and high-resolution TEM images (right bottom) for Dy3+-doped, Sm3+-doped, and Tb3+-doped Cs2AgInCl6 NCs.
