Abstract
A connection between the structure and the electrical and luminescent properties of polyaniline (PANI)–GaSe hybrid nanocomposites is investigated.
By XRD and conductivity measurements, we have found that the nanocomposite is formed only in the interval of GaSe contents 8–22.5%. The addition of GaSe decreases the conductivity by 5–7 orders, by preserving the semiconductor behavior. The emission bands in GaSe–PANI nanocomposites are essentially shifted as compared with those in pure GaSe. The XRD investigation indicates a decrease in the average size of GaSe crystallites during the formation of the composite. A mechanism of interaction of polyaniline with gallium selenide nanoplates is proposed.
