Photo/electroluminescence and electron transport properties of new zinc complexes
Source abstract
Abstract
Abstract Two new zinc complexes were prepared and their electro-optical properties in the fabrication of an organic light-emitting diode (OLED) has been demonstrated. The Forster radius ( R F ) is in the range of 2.79–2.87 nm, and the recorded absolute quantum yields are in the range from 0.69 to 0.73 for those complexes in the solution state. In this work, for the first time, we investigated the effect of various time measurements on the electron mobility of devices with space-charge-limited current (SCLC) method. The results of this study showed that mobility of the samples over time has declined. It has been proposed that this is due to increasing at the number of traps density of state (DOS). The results of the simulations were compared with experimental data of the current density-voltage. Finally, a good match between the simulation and experimental results has been achieved.
