Paper Abstract

Radiation induced phosphorescence of UV window materials has been identified as a source of background signal in UV detectors for as long as these detectors have flown in space, but there is little detailed knowledge of the spectrum, decay time constants or thermal dependence of the phosphorescence. We present initial results of a study undertaken to characterize this source of background signal, including spectra, decay timescale analysis, and preliminary assessment of depopulation/deexcitation techniques. The ultimate goals of this study are to identify and evaluate phosphorescence mitigation techniques and to identify the source of the phosphorescence in optical materials.
