LiNbO3 thin films at different stirrer time: synthesis using chemical bath deposition (CBD) method

Chemical bath deposition (CBD) technique is used to prepare lithium niobate (LN; LiNbO3) nanostructures. The deposition process was maintained over a quartz substrate at different chemical interaction times (3, 6, 9, 12 and 15 h) using the CBD method. The structural properties showed that sample stirring for 12 h resulted in the LN crystalline hexagonal peak at the (012) diffraction plane at 2 theta = 23.75. Scanning electron microscopy showed that the samples became smoother, more homogeneous and showed a better distribution with increasing chemical interaction time. As the chemical interaction time increased, atomic force microscopy revealed a reduction in the grain size and an increase in the surface roughness. The Fourier transform infrared spectroscopy results confirmed the formation of the LN material and agreed with X-ray diffraction findings.

Automated summary
