Reestablishing the photoluminescence lab at ISOLDE: Is there a link between photoluminescence and emission channeling?

Photoluminescence (PL) is an optical, non-destructive technique that can be used to characterize a material’s band structure, however, it can be misleading. Implanting samples with radioactive probes at ISOLDE allows for a clear chemical classification of a peak in a PL spectrum as its intensity changes with time. In this work is presented the reestablishment of PL setup at ISOLDE and progress towards its thorough testing. The samples used for this testing were previously used in emission channeling (EC) experiment allowing for a simultaneous search for a link/correlation between PL, a global technique, and EC, a local technique. The work developed led to a fully functional PL setup with multiple python scripts that automate part of the measuring and analysis processes. From the obtained spectra, evidence was found for a link between PL and EC.
