We observed the hole transfer and confirmed the formation of charge transfer state in CsPbBr3@ZnS core–shell type NCs. The Auger recombination is largely suppressed, endowing the hetero-nanocrystals with unique optical gain properties.

Abstract The irradiation of [Au(CN)2]- in oxygen-saturated acetonitrile leads to photooxidation of Au(I). In the presence of additional chloride [Au(CN)2CL2]- is formed with φ= 0.5 x 10-4 at λirr = 254 nm. It is assumed that [Au(CN)2]- in its metal-to-ligand charge transfer state undergoes an excited state electron transfer to oxygen in the primary photochemical step.
