Photoluminescence and Raman evidence for mechanico-chemical interaction of polyaniline-emeraldine base with ZnS in cubic and hexagonal phase

► Mechanico-chemical interaction of polyaniline-emeraldine base with ZnS forms a hybrid material. ► One used ZnS in two structural forms, cubic and hexagonal. ► The hexagonal structure was obtained from the cubic structure annealed in vacuum at 1050 °C. ► The hybrid material was studied by photoluminescence and Raman spectroscopy. ► A charge collection process activated by the presence of polymer molecules is demonstrated.
