Synthesis and characterization of nanostructure calcite thin films deposited by dip coating

Abstract

In this report we present the synthesis of calcite thin films on pre-cleaned glass substrate by alternate dipping it in a two different calcium metal salt solution and a base solution. The precursor effect on deposited calcite thin films were studied by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), Fourier Transform Infrared Spectroscopy (FTIR) and Ultraviolet–visible (UV–Vis) spectroscopy techniques. From the XRD results it is confirmed that the phase purity calcite thin films were deposited. FESEM technique were used to study the microstructure of surface morphology of deposited thin films. It was seen that with change in molarity of calcium metal salt solution a micro/nano flower morphology changed from blurred to sharp morphology structure in the microstructures studied by the FESEM technique. The change in surface morphology with calcium metal salt solution are discussed in terms of nucleation and growth of film on the substrate. Calcite has attractive possibility to have application in bio-photonics and bone remediation due to its non-toxic and biocompatible nature.
