TiO2 nanoparticles doped with different concentrations of cobalt (4, 8, 12 and 16 %) were synthesized by sol–gel method at room temperature appropriate reactants. In general, can exist in anatase, rutile, brookite phases. this present study, we used titanium tetra iso propoxide 2-propanol as a common starting materials the obtained products calcined 500 °C 800 to get anatase rutile phases, respectively. The crystalline sizes undoped observed X-ray diffraction (XRD) analysis. functional...
A refractive lens is one of the simplest, most cost-effective and easily available imaging elements. Given a spatially incoherent illumination, can faithfully map every object point to an image in sensor plane, when distances satisfy conditions. However, static limited depth focus, beyond which point-to-point mapping only be obtained by changing either location lens, or sensor. In this study, focus mode has been expanded using recently developed computational reconstruction method,...
A new lasing molecule BPTFT was synthesized by substituting furan to the central thiophene ring of BP3T. It exhibits better rigidity and optoelectronic properties, is suitable develop an electrically pumped organic laser.
The present study provides the first reports on electrospinning of TiO2–ZnO–graphene composite nanofibers for photovoltaic and biomedical applications. These were characterized by spectroscopic microscopic techniques to evaluate morphologies phases. fiber diameter was found be ∼210 nm. graphene content maintained in range 0.2–0.7 weight percent. It observed that when increased beyond 0.7 percent, continuous morphology lost. Raman spectroscopy used confirm presence graphene. Conductivity...
Biphenylyl/thiophene systems are known for their ambipolar behavior and good optical emissivity. However, often these alone not enough to fabricate the commercial-grade light-emitting devices. In particular, our recent experimental theoretical analyses on three-ring-constituting thiophenes end capped with biphenylyl have shown electrical properties but lack of properties. From a materials science perspective, one way improve is modify structure integrate it additional moieties. years, furan...
Metal organic complexes, diaceto bis benzimidazole cobalt(II) and copper(II), are synthesized by a simple chemical route. The powders doped in PMMA with 1, 3, 5 wt% deposited as free standing films of thickness ∼1 μm. For theoretical simulation, metal complex (MOC) embedded into the matrix is subjected to polarizability hyperpolarizability calculations using PM6 algorithm MOPAC2012 package. It found that minimum interaction distance between MOC about 34 nm does not vary respect dopant....
The present study demonstrates a facile approach by which TiO2-graphene nanocomposites can be processed into bulk powders via molten salt technique. A detailed had been performed to elucidate the effect of graphene content (0.2–10 wt%) in these and its impact on opto-electrical properties. From analysis an intrinsic correlation between conductance composite has explained basis relative band gap work function Fluorescence spectroscopy measurements showed excitonic intensity lower indicating...
Abstract A detailed understanding of charge transport at the interface is necessary to explore potential organic field‐effect transistors. This can be realized by adequately analyzing trap states interface. In present work, rubrene‐based transistors have been fabricated with three different interfaces. The device properties are used along a technology computer‐aided design deduce density quantitatively. transfer characteristics simulated using double Gaussian and fitted experimental data...
Abstract Direct x-ray detectors using thermally evaporated pentacene thin-films are fabricated in Schottky and coplanar configurations analysed for low dose rates. In both configurations, the induced photocurrent is found to be five orders of magnitude greater than theoretically evaluated threshold value that may reflect possible internal gain mechanism. Coplanar showed unstable characteristics; on other hand, photodiode structure stable response thus allowed proceed sensitivity...
