Abstract

Mn-doped nanocrystalline ZnO (MnxZn1-xO) was incorporated in the polyvinylidene fluoride thin film for obtaining the free-standing flexible film by the sol-gel technique. The effect of Mn-ZnO loading on the optical and microstructural properties of the Mn-ZnO/polyvinylidene fluoride (PVDF) composite films was studied critically for the as-deposited and the poled samples. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy were carried out to study the bonding environment. The XPS spectra recorded for poled samples from the fluorine-terminated surface showed a very strong peak at approximate to 695 eV for F1s arising due to C-F bonds. Raman studies showed the presence of the predominant phase of PVDF in the sample. Peaks related to ZnO nanocrystals were also observed in the Raman spectra. Photoluminescence spectra indicated a strong emission band at approximate to 2.79 eV in the ultraviolet region arising out of near band edge emission of free excitons.
