Optical properties of (ZnTiO3)/Epoxy Nanocomposite Thin films

Two layers of epoxy reinforced with nano- Zinc Tetanet (ZnTiO3) uniform thin films have been prepared using a spin coating technique on glass floors, dispersion and magnetic stirring techniques are used to prepare the nanocomposites, FTIR was employed to aid interpretation of results with a fixed thickness and proportions by weight (0Wt%,1Wt%,2Wt%,3Wt%,4Wt%) ZnTiO3additives.The optical characteristics were studied by measuring the transmittance and absorbance spectrometry as a function of the wavelength (200-1100) nanometers. The results of the transmittance were very high, and high transparency in infrared (IR) radiation was measured by the FTIR and UV-VIS measurements. The optical properties included the calculations of the energy gap; some optical constants were also carried out, which included absorption coefficient making it Suitable for applications of solar cells

In this paper,Zinc oxide was dopped by various concentrations (5,10,15,20,25) % wt, silicon oxide The mixture was deposited on glass substrate by laser pulse deposition at room temperature to obtain (Zn2SiO4) thin films .The optical properties of thin films prepared on spectral absorption and transmission recording were studied at the wavelength range (200- 1100) nm. Some of the optical constants, including absorptance, transmission, absorption coefficient, and energy gap are calculated before and after annealing at (400 ̊C) for (1 hr). Absorptance values and absorption coefficient increase after doping and transmission and energy gap decreases after the doping. Absorbance values and absorption coefficient decreases after annealing and transmission and energy gap increase after the annealing . http://dx.doi.org/10.25130/tjps.24.2019.015

AbstractNovel Si-Al nanocomposite thin films were made by radio frequency co-sputtering of Si and Al with Al content from 0 at.% to 69 at.%. Microstructure and optical properties of the films were characterised by conventional and high resolution transmission electron microscopyand spectrometry in the wavelength range from 200 to 3000 nm. The film microstructure consisted of Al nanoparticles (2-9 nm) embedded in an amorphous Si-Al matrix. Optical absorption spectra of the films up to 50 at.% Al exhibited a sharp absorption peak below500 nm and relatively low absorption above 500 nm. In addition, the absorption peak shifted towards longer wavelengths and the general absorption above 500 nm increased remarkably as Al content increased. For the Si-69at.%Al films, however, an absorption plateau appeared between 300 nm to 700 nm and a second weak and broad absorption peak appeared at around 900 nm. The results are analysed and compared with the optical absorption predicted by various effective medium theories.

ABSTRACTAblation of ceramic silicon carbide with 351 nm excimer radiation was used to depositSIC films on fused silica and on sapphire. For deposition temperatures above 850° C, diffraction shows the films to be crystalline with the [111] axis preferentially oriented normally to the film. Optical spectra show an indirect energy gap at 2.2 eV, near that for the cubic polytype, although the 200 diffractions are absent. Room temperature resistivities range between .02 to .1 Ωcm. Deposition below 600° C yields amorphous SiC with no diffraction bands, low and variable optical band gap and very high resistivity.
