M. A. Fakhri, Evan T. Salim, U. Hashim, Zaid T Salim, Mohammed A. Minshed; Effects of Different Parameters on XRD Properties of Nano and Micro LiNbO3 Using Chemical Method ; Advanced NanoMaterials and Technologies for Energy Sector; 2017:1(2):98-106
Lithium niobate (LiNbO3) nano and micro structures are deposited using spin coating method on quartz substrate. The precursor solutions are prepared under different time of stirring (8, 24 and 48h). The precursors are deposited by spin coating at 3000 rpm for 30sec and 0.5 mol/L. The samples are analysed by X-ray diffraction. The results show that as mixing time increases, the XRD starts to become structurally more regular, and it is found that the best mixing time was 48 h. The effects of annealing temperature (400, 500 and 600 °C) on the structural properties is studied, to reach the ideal conditions for the preparation of optical waveguides.
