This paper focused on the effect of sol–gel stirring duration on the properties nanostructured lithium niobate (LiNbO3) films grown by sol–gel method. Nanostructured LiNbO3 film was deposited on quartz substrate using sol–gel deposition technique. The precursor solution has been prepared with maximum stirrer times of 48 h. The structural, morphological and optical properties of grown films have been investigated using X-ray diffraction, scanning electron microscopy, atomic force microscopy, optical study through Raman spectroscopy, UV–Visible and photoluminescence (PL). The measurements showed that the structure was crystalline in nature and the grains was distributed regularly within the film. This observation is typically used in optical waveguides and other optoelectronics applications. Raman spectroscopy proved a multi dominated Raman-active phonons with the main diffraction peaks corresponding to E(LO1), E(LO7), E(LO8), E(TO3) and E(TO4).
