Eu${}^{2+}$: a suitable substituent for Pb${}^{2+}$ in CsPbX${}_3$ perovskite nanocrystals?

Firoz Alam, K. David Wegner, Stephanie Pouget +4

Eu${}^{2+}$ is used to replace toxic Pb${}^{2+}$ in metal halide perovskite nanocrystals (NCs). The synthesis implies injection of cesium oleate into a solution of europium (II) bromid…
