文摘

We fabricated organic/inorganic nanocomposites P3HT@TiO2 NRs and P3HT@ZnO/TiO2 NRs. The optical properties of P3HT are strongly influenced by inorganic nanostructures. The nanocomposites show strong light absorption and evident PL quenching. The organic/inorganic nanocomposite exhibit high photoactivity. ZnO/TiO2 NTs are superior to TiO2 NTs in composing nanocomposites with P3HT.
