Fig. . Schematic presentation of synergic coupling of SCO and luminescence. Energy transfer from the excited state of the donor to the HS-SCO complex doesn't occur due to poor spectral overlap and thus the luminescence of the donor is retained (right). For LS-SCO complex spectral overlap is more leading to quenching of luminescence of the donor (left). Scheme 1. Schematic representation of the capping ligands mentioned in this review for the synthesis of 0D SCO-luminescence complexes.
