Project description

Over the last few years, photoluminescence spectroscopy gained increasing interest as characterization technique at Ghent University for the development and study of optical materials. The research of the users that installed the 2 current spectrometers diversified from materials for lighting and display applications to integrated photonics, photocatalysis and luminescent sensing, in part by the influx of new researcher on prestigious grants, in part by extending the user base. To accommodate the resulting need for extended capabilities and more measurement time, we propose to extend one of these spectrometers with a new detection arm and bespoke light sources for time-resolved or transient photoluminescence spectroscopy. Implementing the most recent, gated detection technology for high dynamic range studies this extension will allow all listed 13 promoters and users to break new ground in their research while almost doubling the available measurement time on the spectrometer.
