A one-pot synthesis of reduced graphene oxide-Cu₂S quantum dot hybrids for optoelectronic devices

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...

Summary: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.
