Abstract

Herein, we report in situ synthesis of zinc sulphide (ZnS) quantum dots in polyphenylene sulphide (PPS) matrix employing facile solid–solid reaction. The resultant product reveals formation of cubic nanocrystalline zinc sulphide structure. The HRTEM confirms the formation of zinc sulphide quantum dots (size ∼ 3–4 nm) embedded in the polymer matrix.
