Název v původním jazyce

Time-resolved luminescence spectroscopy of solid-state scintillators excited by nanosecond XUV pulses

Popis výsledku v původním jazyce

Here we present preliminary results of time-resolved spectroscopic studies of novel scintillation materials using an advanced instrumentation. The temporal response of visible luminescence excited by ionizing radiation is an important property of a scintillator. Namely, a presence of slow decay components caused by defects in the crystal lattice can significantly contribute to the total luminescence output and thus limit the applicability of a scintillator in high-speed detectors of ionizing radiation.Therefore, the assessment of temporal characteristics of the scintillation response is of great importance in scintillator research. A previously reported time-domain spectrometer utilizing a compact pulsed source of extreme ultraviolet (XUV) radiation was used for the measurement of UV-VIS luminescence decays. The XUV source is based on laser-produced plasma from a nitrogen gas-puff target. The plasma is induced by high energy pulses from a Nd:YAG laser (1064 nm, 0.7 J, 4 ns). The sourc
