The fabrication of flexible organic photovoltaics (OPVs) which utilize transparent and conducting single walled carbon nanotube (SWNT) thin films as current collecting electrodes on plastic substrates in zinc oxide nanowire (ZnO NW)/poly(3-hexylthiophene) (P3HT) bulk heterojunction photovoltaic devices is reported. The bulk heterojunctions for exciton dissociation are created by directly growing ZnO nanowires from solution on the SWNT electrodes and spin coating the P3HT polymer. A maximum OPV power conversion efficiency of similar to 0.6% was achieved. Our results indicate that nanotube-nanowire hybrids fabricated via solution based methods are promising for optoelectronic and energy harvesting devices.


Phase transition of chemically synthesized FePt nanoparticles under high pressure
ŞİMŞEK, TELEM; Karci, Ozgur; ÖZCAN, ŞADAN (The Scientific and Technological Research Council of Turkey, 2018-01-01)
We present the results of a study related to phase transformation of chemically synthesized FePt nanoparticles under high pressure from face-centered cubic into face-centered tetragonal structure. As-synthesized nanoparticles are around 4.5 nm and show superparamagnetic behavior at 300 K. After annealing under 60 bar pressure of hydrogen at 400 degrees C for 2 h, nanoparticles exhibit strong ferromagnetic behavior with 5391 Oe coercivity. Results show that high-pressure annealing lowers the decomposition te...
Electrochromic and photovoltaic applications of benzotriazole bearing donor acceptor type conjugated polymers
Baran, Derya; Toppare, Levent Kamil; Department of Chemistry (2010)
Organic semi-conductors are of great interest since these compounds can be utilized as active layers in many device applications such as ECDs, LEDs and solar cells. Incorporating the benzotriazole units into the polymer backbone enhances the optical properties of donor units. Hexyl thiophene and pyrrole are commonly used as electron donor materials. Benzotriazole can be coupled to hexyl thiophene or pyrrole to yield materials which can be polymerized to give donor acceptor type polymers. These materials are...
Indium tin oxide nanoparticles as anode for light-emitting diodes
Çırpan, Ali (Wiley, 2006-02-15)
Thin films of indium tin oxide (ITO) nanoparticles have been investigated as anode materials for polymer light-emitting diodes. A luminance efficiency (0.13 cd/ A), higher than that (0.09 cd/A) obtained in a control devices fabricated on conventional commercial ITO anodes were found. The thin films were made by spin coating of a suspension followed by annealing. The ITO nartoparticle films have a stable sheet resistance of 200 ohm/sq, and an optical transmittance greater than 86% over the range of 400-1000 ...
Germanium determination by flame atomic absorption spectrometry: An increased vapor pressure-chloride generation system
Kaya, Murat; Volkan, Mürvet (Elsevier BV, 2011-03-15)
A new chloride generation system was designed for the direct, sensitive, rapid and accurate determination of the total germanium in complex matrices. It was aimed to improve the detection limit of chloride generation technique by increasing the vapor pressure of germanium tetrachloride (GeCl4). In order to do so, a novel joint vapor production and gas-liquid separation unit equipped with a home-made oven was incorporated to an ordinary nitrous oxide-acetylene flame atomic absorption spectrometer. Several va...
Energy band gap and oscillator parameters of Ga4Se3S single crystals
Qasrawi, A. F.; Hasanlı, Nızamı (Elsevier BV, 2007-06-01)
The optical properties of the Bridgman method grown Ga4Se3S crystals have been investigated by means of room temperature, transmittance and reflectance spectral analysis. The optical data have revealed an indirect allowed transition band gap of 2.08 eV. The room temperature refractive index, which was calculated from the reflectance and transmittance data, allowed the identification of the dispersion and oscillator energies, static dielectric constant and static refractive index as 21.08 and 3.85 eV, 6.48 a...
