Staff exchanges

THE STAFF EXCHANGE BETWEEN SUT AND UDUR


The Staff exchanges between SUT and UDUR for training and knowledge exchange is still ongoing. The SUT members spent already 215 days (7.68 person-month) in total on training at UDUR.   The total exchange visit time of people from UDUR at SUT reched 134 days (4.78 person-month).

SUT members visit at UDUR
A. Kurowska – 22.05.2016 – 22.07.2016
P. Zassowski – 22.05.2016-22.07.2016
K. Karoń – 18.11.2016 – 16.12.2016

The general scope of the training was divided into two parts: the first one was an optical characterization of π-conjugated organic compounds like registration of the fluorescence spectra in solvents characterized by different polarity or in the solid state. The second was training in the area of molecular photophysics, including concepts of singlet and triplet excited states, fluorescence and phosphorescence emission. Measurements of above-mentioned phenomena using both steady-state and time-resolved luminescence. Such set of measurements gave a concept how use obtained information to choose materials suitable for OLED emitters. In later training, SUT scientists learned also how to prepare and analyze OLED devices. Before arrival, SUT researchers were choosing which is more important for them at the moment and suitable training was prepared for them.

The goal of the training was to gain different electrochemical skills to be brought back to Durham and used in the comprehension of OLED emitting materials.In order to research the mechanism of light emission within OLED device structures, a comprehensive understanding of HOMO-LUMO levels are required so that each layer within the OLED structure can be perfectly engineered to facilitate charge injection. There is a long precedence for determining HOMO-LUMO levels using cyclic voltammetry (CV) so the training and expertise were required to obtain meaningful results. Additionally, the training in UV-Vis-NIR, EPR, IR and Raman spectroelectrochemistry were conducted to analyze the formed charge carriers and the molecular structure during doping. In the end,an Electrochemical Impedance Spectroscopy training was provided for two persons to characterize the change in conductivity of materials during the doping process.
