Steady-state photoluminescence (PL) spectra of (a) Au@Cu7S4, (b) Au@CdS, (c) Au@ZnS, and (d) Au@Ni3S4. The results of their pure counterparts are also included.

Caption

Under light illumination, the nanostructures were found to have high photoluminescence (PL) activity, revealing them to be highly capable of absorbing light and generating electrons and holes as charge carriers.
