A study has been conducted on the characterization of optical properties of thin films from lidah mertua (Sansevieria trifasciata) with dip coating method. The dip coating method was applied with different temperature and different time immersion treatments. The measuring variables in the manufacture of this thin film were tested based on the optical properties of their absorbance value of the extract and the thicknessof thin film. The absorbance spectral of extraction pigments were measured using UV-Vis in the wavelength range 350 nm to 700 nm. The results of the measurements showed that the extract of the S. trifasciata has high absorbance. Beside that, the minimum coating thickness is produced by a concentration of 12.5% with a 5 minute immersion time of 520 nm.

Nanocrystalline titanium dioxide (TiO2) thin films have been prepared by dip coating method. The TiO2 thin films have been coated on glass substrate and annealed at 400, 450 and 500° C respectively. The X- ray diffraction pattern shows that TiO2 nanocrystalline thin films are of anatase structure and the grain size is found to be in the range of 20-35 nm. The annealed films have been observed to be nanocrystalline in nature and the crystallinity has been observed to improve on annealing. The surface topography of the films has been studied using atomic force microscope. The optical properties have been studied using transmittance spectra. The band gap has been found to lie in the range of 3.70 to 3.83 eV depending on the annealing temperature.

In this paper, the influence of immersion time on the structural and optical properties of SnO2 thin films was investigated. A series of samples was deposited by Sol-Gel dip coating method onto glass substrates. The number of layers was fixed at 03, but the immersion time was varied between 01 to 10 minutes. The samples [(3 layers) - SnO2 / glass] were submitted to thermal treatments in air at 500°C during 2h. The specimens are characterized by Raman spectroscopy and UV-Visible spectroscopy. Raman spectroscopy show that the thin films of SnO2 obtained at 06 and 10 minutes of immersion time, are crystallizes in rutile phase. The obtained results of optical analysis showed that the SnO2 thin films are transparent (77-85%) in the visible region and the values of the optical band gap varied from 3.81eV and 3.86 eV.
