Abstract
This paper deals with preparing of Lithium-Niobate thin films based on Sol-Gel technique on a substrate made of quartz, samples have been deposited under three different stirrer times. At 3000 round per minute of spin coating strategy, the deposition processes have been accomplished. The results showed an enhancement in the crystalline structure of the prepared samples with increasing the duration of stirrer time. The AFM measurement has assured that the structure of the prepared samples is more regular distributed, homogeneous and crack-free in their structures. Further, measurements and calculations of lattice constant, energy band gap, refractive index, and optical dielectric constant are also considered and agreed with experimental data collected by the characterized samples.
