Organic semi-conductors are widely used in the development and manufacturing of certain optoelectronics. However, these materials are susceptible to photodegradation in the presence of oxygen. This is due to a polymer’s populated triplet state creating singlet oxygen. In recent years, the use of plasmonic metal nanoparticles in the polymer systems or deposited on a substrate, have yielded polymer films that degrade much slower than films with the polymer alone, as long as there is good overlap with the plasmon of the metal and the emission of the polymer. Since this overlap is crucial, tunability of the plasmon is essential to “fit” various polymer systems. The research presented here provides methodology for the facile manufacturing and tuning of metal deposits for such purposes. Not only this, but through increasing the tunability of these plasmons we are able to better image various emissive pathways and species better in a polymer system deposited on film.
