In recent years, lead halide perovskites have attracted the attention of researchers due to their outstanding photovoltaic and optoelectronic properties. In addition, the synthesis of controlled nanostructures opens new possibilities to design opto-electronic and quantum optics devices. In particular, recent 0D colloidal nanocrystals have shown single photon emission at room temperature and have enlarged the domain of future applications of perovskite materials.

The presence of lead and other atoms, such as iodine, is at the base of the large spin–orbit coupling of these materials. The giant conduction band splitting, instead of the standard valence band splitting, is the clear signature of this strong coupling. The interplay between time-reversal symmetry and the lack of spatial inversion symmetry makes the existence of more subtle effects in perovskite materials, such as Rashba–Dresselhaus coupling, possible. These large spin–orbit interactions associated with remarkable optoelectronic properties open the path to spin manipulation and the realization of new devices at the edge of optoelectronics and spintronics.
