A Novel Mechanism of Optical Spectrum Formation in the Cs2NaInCl6 Doped with Sb and Er
{{output}}
We present a mechanism describing the formation of the optical spectrum in double halide perovskites (DHPs), specifically Sb- and Er-doped Cs2NaInCl6. Optical measurements conducted at the Deutsches Elektronen-Synchrotron (DESY) facility between 10 and 300 K h... ...
