Lattice Doping of Lanthanide Ions in Cs2AgInCl6 Nanocrystals Enabling Tunable Photoluminescence
Elemental analysis of Ln3+ ()-doped Cs2AgInCl6 NCs. (a) Survey XPS spectra for the undoped and Dy3+-doped, Sm3+-doped, and Tb3+-doped Cs2AgInCl6 NCs. (b–e) High-resolution XPS spectra for Cs 3d, Ag 3d, In 3d, and Cl 2p, respectively. (f) High-resolution XPS spectra for the Dy3+ 4d, Sm3+ 3d, and Tb3+ 4d for Dy3+-doped, Sm3+-doped, and Tb3+-doped Cs2AgInCl6 NCs, respectively.
