Study the Luminescence of
Phosphors and Doped Materials
It is well known that some
materials emit light when their electrons are excited by electrons or
photons. We are calculating how doping phosphors and ordinary materials
can cause their luminescence to change. This work is done in
collaboration with Professor
Paul Holloway and Professor
John Reynolds (University of Florida) and is supported by a MURI
grant from the Army Research Office.
- The end goal of this project is to be able to
predictively calculate absorption
and emission spectra for novel materials using computational
techniques.
- To accurately calculate emissions, the
absorption spectra first need to be calculated correctly.
- We have obtained accurate results in
compairison to experiment for two polymers: PPP-R10 and PPP-OR11.
- Excitations are explored for a cyanovinalyne
class of oligomer chains as well as the effect of substitutions on that
chain.
