Time-resolved photoluminescence spectroscopy of organic-plasmonic hybrids

Research output: Contribution to conference without publisher/journalConference abstract for conferenceResearch

Abstract

We study the optical properties of organic thin films and crystalline organic nanofibers as well as their interaction with plasmonic materials by means of laser-scanning fluorescence lifetime imaging microscopy (FLIM) and time-resolved photoluminescence spectroscopy (TR-PLS). The aim of our research is to understand and developed organic-plasmonic hybrid systems with tailored optical and plasmonic properties such as wave-guiding, enhance second-harmonic response and lasing. We are able to image, gather information about the fundamental coupling mechanism, as well as study charge-carrier dynamics in such systems.
In this contribution we will show how the interaction of organic nanofibers placed on top of regular arrays of nanostructures leads to a significantly enhanced second-harmonic response and, at the same time, an increased decay rate of the photoluminescence lifetime.
