▎ 摘　　要

We demonstrate a facile one-pot approach for the synthesis of reduced graphene oxide (rGO)-cuprous sulfide quantum dot (Cu2S QD) hybrids, wherein the reduction of GO and the growth of Cu2S QDs on graphene occur simultaneously. The as-synthesized rGO-Cu2S QD hybrids exhibit an excellent photoelectric response and efficient electron transfer from the Cu2S QDs to the rGO sheets.
