Abstract In the current work, structural and optical properties of thermally evaporated 3-(2-Benzothiazolyl)-7-(diethylamino) coumarin [Coumarin 6 (C6)] thin films on a pre-cleaned quartz substrate were studied as function annealing temperature. The influence structural, morphological, molecular structures was investigated by x-ray diffraction (XRD), atomic force microscopy (AFM), Fourier transform infrared (FTIR) spectroscopy, respectively. XRD AFM results confirmed that as-deposited...
Abstract Starting with Coumarin-6 dye, two novel D-π-A organic dyes C6X and C6N have been designed by attaching carboxylic acid cyanoacrylic groups as anchoring to Coumarn-6 respectively, understand their potential use in dye-sensitized solar cells (DSSCs). The electronic structure photophysical photovoltaic properties of the were studied using density functional theory DFT time-dependent TD-DFT Becke3-Parameter-Lee–Yang–Parr (B3LYP) 6-31G (d, p) basis set. Optimized (highest occupied...
Abstract Tin oxide compounds have been highly studied due to their important properties. Oxide (II) SnO compound is considered an ideal p-type conductive material, with large carrier mobility. It getting a lot of attention in next-generation electronic applications. In this work, the thin film was deposited on polyethylene terephthalate (PET) substrate by thermal evaporation method. The X-ray diffraction pattern revealed amorphous structure SnO/PET film. purity confirmed using Raman...
With a combination of outstanding properties and wide spectrum applications, graphene has emerged as significant nanomaterial. However, to realize its full potential for practical number obstacles have be overcome, such low-temperature, transfer-free growth on desired substrates. In most the reports, direct is confined either small area or high sheet resistance. Here, an attempt been made grow large-area directly insulating substrates, quartz glass, using magnetron-generated microwave plasma...
In this study, 4-phenylthiazol-2-yl-(phenylhydrazono) acetonitrile (PTPA) azo dye was synthesized and studied from optical electrical point of view. The tautomerization phenomenon the PTPA clarified using one-dimensional (1D) two-dimensional (2D) nuclear magnetic resonance (1HNMR 13C NMR), absorbance (UV-Vis), emission, Fourier transform infrared spectroscopy (FT-IR). X-ray diffraction (XRD) evaluations were indicated that in powder thin films crystallizes a monoclinic system structure with...
Abstract Bismuth oxyhalides are becoming a promising contender for photovoltaic applications due to its non-toxic nature and decent optical properties. This study mainly deals with clarifying the effects of phase transformations on structure, optical, electrical properties BiOI thin film prepared via dip-successive ionic layer adsorption reaction (SILAR) method at different annealing temperatures ranging from 100 400 °C. Therefore, significant (i.e., existence Bi 7 O 9 I 3 5 have been...
Alternating current (AC) conductivity and dielectric properties of thermally evaporated Au/PtOEP/Au thin films are investigated each as a function temperature (303 K–473 K) frequency (50 Hz–5 MHz). The dependence AC follows the Jonscher universal dynamic law. AC-activation energies determined at different frequencies. It is found that correlated barrier hopping (CBH) model dominant conduction mechanism. variation exponent s with analyzed in terms CBH model. Coulombic height Wm, distance Rω,...
