In this paper, we have reported the optical non destructive technique, which uses double exposure digital holographic interferometry (DEDHI) together with simple mathematical interpretation, which instantly situates to the thickness of thin films, deposited mass, stress to substrate and fringe width for different deposition times. Here, the stainless steel substrate was exposed for different intervals of time. It is observed that the fringe width, stress to substrate changes with changing the time of deposition. This effect is due to the increase in thickness of CdXZn1−XS (X=0.3) thin films. Thus, holographic studies show sensitivity to deposition time and concentrations of solution. © 2016 Elsevier Ltd

In this paper, we have used double exposure digital holographic interferometry (DEDHI) technique for hologram recording of electrochemical synthesis of the CdS and ZnS thin films materials. As synthesis CdS and ZnS thin films are characterized by different characterization techniques such as X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), optical band gap, and contact angle measurement. Further recording of the holograms has been carried out with different deposition time of CdS and ZnS thin films, and we have used mathematical relation between stress, mass deposited thickness of thin film and fringe width. It is seen that the fringe width, mas of deposited samples, stress to substrate changes with the time of deposition. © 2017 Springer Science+Business Media New York

Dysprosium doped Co-Zn ferrites were synthesized by sol-gel auto combustion method. These synthesized compounds were characterized by using XRD, SEM, FTIR, EDS, TGA-DTA and TEM. TGA weight loss in the region of 100-200°C and this loss is due to autocatalytic oxidation reduction reactions of nitrates with glycine. The composition Co 0.5Zn 0.5Fe 2-xDy xO 4 (x=0.075) shows fibrous reticulated mesh like morphology. The average grain size increases with increasing the Dy content in the Co-Zn ferrite. The XRD study of Dy doped Co-Zn ferrite shows in Cubic spinel phase. Particle size obtained from TEM analysis was found to be 30-40 nm. The FTIR spectra showed the characteristic of two strong absorption bands at 560 cm -1 corresponds to intrinsic stretching vibrations of the metal at the tetrahedral site and lowest band is observed at 455 cm -1 corresponds to octahedral site. © 2012 Elsevier B.V.

A Ni2+-TiO2 photocatalyst, efficient and highly active in sunlight has been prepared by a simple hydrothermal method using titanium isopropoxide (TTIP) precursor. The synthesized nanoparticles (NPs) have been analysed to determine its structural, optical, morphological and compositional properties using X-ray diffraction, Raman, UV-DRS, photoluminescence, XPS, TEM and EDS. The EDS micrograph confirms the existence of Ni2+ atoms (0.65, 1.32 and 1.60 wt.%) in the TiO2 matrix. The average particle size obtained from TEM is 8-11 nm and is in good agreement with XRD results. Raman bands at 641.44 cm-1, 517.42 cm-1 and 398.43 cm-1 further confirm pure phase anatase in all samples. XPS shows the substitution of Ti4+ ions by Ni2+ ions in the TiO2 host lattice. The photocatalytic activity of these nanoparticles have been studied using malachite green dye under UV light, visible light and direct sunlight. The crystallite size and band gap decreases with increase in Ni2+ concentration which increase its catalytic activity under sunlight. The photocatalyst, Ni2+-TiO2 (1.60 wt.%), shows excellent photocatalytic activity in the visible and direct sunlight and hence it is a promising for environmental friendly photocatalytic applications.

Digital holographic interferometry technique is used to determine elastic modulus of silica aerogels. Tetramethoxysilane precursor based Silica aerogels were prepared by the sol-gel process followed by supercritical methanol drying. The alcogels were prepared by keeping the molar ratio of tetramethoxysilane: methyltrimethoxysilane: H2O constant at 1:0.6:4 while the methanol / tetramethoxysilane molar ratio (M) was varied systematically from 12 to 18. Holograms of translucent aerogel samples have been successfully recorded using the digital holographic interferometry technique. Stimulated digital interferograms gives localization of interference fringes on the aerogel surface and these fringes are used to determine the surface deformation and Young's modulus (Y) of the aerogels. © 2016 Author(s).

Magnetic nanoparticles of ZnO@CoFe2O4 photocatalyst has been synthesized by polyol reflux method for degradation of organic dyes. The synthesized MNPs were characterized using XRD, IR, TEM and AGM for elucidate its structural, morphological and magnetic properties. The BET analysis was also carried out for determination of its surface area. The lattice constant, X-ray density, surface area and volume of MNPs were determined from XRD patterns. The synthesized MNPs were explored to study its photocatalytic activity using malachite green (diphenyl type), thymol blue (azo type) and methyl orange (azo type) dyes. This synthesis method is simple and fast for synthesis of dispersible and magnetically separable photocatalyst. © 2016 Elsevier Ltd.

A pure-phase anatase nanocrystalline TiO2 has been prepared at lower temperatures from aqueous peroxy titanium complex solution using titanium (III) chloride as precursor. The study on the reflux method has been carried out to investigate the effect of refluxing conditions on the characteristic properties of TiO2 and it has shown significant effects on the final product. The X-ray diffraction and UV-vis characterisations reveal that as refluxing time extended, the crystallite size increased and variation is found in bandgap energies. This is attributed to the effect of refluxing during the synthesis of nanocrystalline TiO2. A detailed study on the reflux method used for the synthesis of nanocrystalline TiO2 is reported. © The Institution of Engineering and Technology 2011.
