Summary on Grant Application Form
It is the purpose of this programme to synthesis improved materials for application in light emitting diodes (LEDs) and as sources of polarised light for liquid crystals (LCDs). This will be achieved by a new concept. New monodisperse photopolymerisable oligomers will be applied to a suitable substrate, macroscopically aligned and fixed as an homogeneous thin solid film network by cross-linking.. The correlation between the chemical structure of these materials, their macroscopic orientation and their physical properties, such as quantum yield, wavelength, bandwidth, thermal and electrochemical stability, as a thin solid film on a substrate between tow electrodes will be systematically investigated in LED configuration. The mechanism of photon and electrical excitation, luminescence and carrier transport properties within thin films will be studied. New addressing techniques will be investigated in collaboration with industrial partners. Multilayer configurations will also be studied as these should lead to higher light output and narrower bandwidths. A variety of measurements will be performed, including temperature dependent current-voltage-light output, complex impedance and spectrally resolved photoconductance. The results of these measurements will be used to model charge injection, transport and recombination processes. The programme is multidisciplinary with a high training content.
