We demonstrate the deposition of amorphous and anatase TiO 2 on indium tin oxide (ITO) substrates via the process of sputtering, and the use of these materials as electron-collecting layers (ECLs) in inverted-type organic photovoltaics (OPVs). Anatase TiO 2 was obtained via vacuum-annealing of as-deposited amorphous TiO 2 at 300°C. No deterioration of optical and electrical...
Fluorescent and phosphorescent organic light emitting diodes (OLEDs) were measured in high magnetic field up to 9T. The current efficiency steeply increased below 100mT as reported but gradually decreased when the field was larger. In the range of 0.1–6.5T, the decrease was proportional to the square of the magnetic field, whereas in the range between 6.5 and 9T, it was proportional to the square...
