Halide alloying and role of central atom on the structural and optical properties of decylammonium germanium 2D perovskites
We report here a novel series of halide alloyed Ge-containing 2D perovskites including decylammonium as organic spacer, namely DA2Ge(Br1−xIx)4. This system forms a continuous solid solution on the halide site with a modulation of the bandgap from 2.74 to 2.17 eV with a rapid decrease up to x = 0.5 f...
