Emissive Bi-doped double perovskite Cs2Ag1-xNaxInCl6 Nanocrystals
No full textWe report the composition-dependent optical properties
of Bi-doped Cs2Ag1 12xNaxInCl6 nanocrystals (NCs) having a
double perovskite crystal structure. Their photoluminescence (PL)
was characterized by a large Stokes shift, and the PL quantum yield
increased with the amount of Na up to 3c22% for the
Cs2Ag0.4Na0.6InCl6 stoichiometry. The presence of Bi3+ dopants was
crucial to achieve high PL quantum yields (PLQYs) as nondoped NC
systems were not emissive. Density functional theory calculations
revealed that the substitution of Ag+ with Na+ leads to localization of
AgCl6 energy levels above the valence band maximum, whereas
doping with Bi3+ creates BiCl6 states below the conduction band
minimum. As such, the PL emission stems from trapped emission
between states localized in the BiCl6 and AgCl6 octahedra,
respectively. Our findings indicated that both the partial replacement
of Ag+ with Na+ ions and doping with Bi3+ cations are essential in order to optimize the PL emission of these systems
