Název v původním jazyce

Time-resolved soft X-ray excited luminescence spectroscopy of solids state scintillators

Popis výsledku v původním jazyce

We present the measurement of luminescence kinetics of scintillators, excited by a table-top soft X-ray source ? laser produced plasma. Plasma is induced by Q-switched Nd:YAG laser (? = 1064 nm, 600 mJ, 7 ns pulse) focused into argon gas-puff target. Scintillators as photon energy converters constitute the foremost X-ray detection component in a wide variety of medical X-ray imaging systems. Thus, their properties are determinative for performance of such devices. Practical use of scintillators is oftenlimited by their luminescence kinetics, i.e. by the speed of radiative deexcitation of luminescent centers. Thus, the investigation of luminescence kinetics plays one of the major role in the development of new scintillation materials. Our contributionto this research consists in development and application of a new spectroscopic technique, which would allow us to measure the luminescence decay within a very wide temporal range (ten ns to > ms), with nanosecond temporal resolution and
