Abstract
A method and device for improving the optical performance (such as time resolution) of scintillation detectors using the optical bleaching technique are disclosed. Light of a selected wavelength is emitted by a light source into a scintillator. The wavelength is selected to meet the minimum energy requirement for releasing of charge carriers captured by the charge carrier traps in the scintillation material. Trap-mediated scintillation components are thus reduced by optical bleaching and the optical performance of the scintillator crystal and the detector is enhanced.
