Abstract
In this manuscript, the physical properties of lithium-niobate films prepared by spray pyrolysis method were deeply studied. The deposition process has been taken over a quartz substrate with employing new raw materials as precursor compounds. Different annealing temperatures were applied during the deposition process. The optical results further analyzed by ultraviolet-visible (UV-Visible) and PL. The results showed that films orientation has energy band gap was measured of 3.9 eV with transmission efficiency ranges between 43 to 78%.
