Degradation Analysis of Blue Phosphorescent Organic Light Emitting Diode by Impedance Spectroscopy and Transient Electroluminescence Spectroscopy

We carried out degradation analysis of a blue phosphorescent organic light emitting diode by both impedance spectroscopy and transient electroluminescence (EL) spectroscopy. The number of semicircles observed in the Cole-Cole plot of the modulus became three to two after the device was operated for 567 hours. Considering the effective layer thickness of the initial and degraded devices did not ...

Organic semiconductor co-crystals: reactivity, mobility, and spectroscopy

Organic semiconductors are of interest because low processing temperatures and cost which make such materials candidates for flexible electronics. The charge transport properties of the material are largely dependent on solid-state arrangement of the molecules. This thesis focuses on co-crystallization as a means to achieve [2+2] photodimerization with organic semiconductors, the impact the co-...

Diagnostics of Organic Compounds Degradation by Optical Emission Spectroscopy

This contribution is focused on the optical emission spectroscopy observations of the DC non-pulsed diaphragm discharge in various water solutions. The emission intensities of the hydroxyl radicals and the atomic lines of some selected elements are investigated. We have also studied the influence of the experimental conditions (for example of the applied high voltage and the discharge power, pH...
