• Developing new OLED technology: An investigation into Excition-Plasmon coupling

The aim of this project is to investigate the enhanced light emission of a host-guest material, which consists of an Iridium based dye and a Gold nanoparticle embedded into a porous silica host. During this project I will first synthesise the host-guest material and then investigate how their excited states interact resulting in enhanced light emission. This research is of importance in the technology industry as it has applications in light emitting devices used in everyday life such as OLED televisions/monitors and general lighting. The use of an Iridium based dye rather than small organic molecules or polymers which are currently used in OLED devices will massively improve the quantum efficiency of the light emission. The ability of the Iridium dye and Gold nanoparticle to produce enhanced and more efficient light emission is why this research is of importance and could be used to improve OLED devices in the future.
