ABSTRACT
Electron-lattice (e-ph) coupling originated from the low-temperature photoluminescence in ZnFe2O4/TiO2 nanocomposite films has been studied. The purely linear character of the e-ph coupling is shown through the Huang–Rhys model within the Franck–Condon approximation. The interfacial coupling capability between the ZnFe2O4 nanoparticles and the TiO2 host lattice is characterized by the Huang–Rhys factors (S0) and the vibrational quantum energy (hΩ). It is found that the Huang–Rhys factors S0 increases with increasing the content of ZnFe2O4 in the TiO2 films and the vibrational energy hΩ is quite in agreement with that in the infrared spectra.
