| Description
| - Pomocí elektron-spinové rezonance byly studovány samozachycené díry v krystalech CdWO4. Bylo zjištěno, že tyto díry jsou buď delokalizovány v prostoru mezi dvěma energeticky ekvivalentními nejbližšími kyslíkovými ionty nebo tunelují mezi nimi. Když teplota vzroste nad 40-50 K, díry jsou teplem uvolněny a mohou být znovuzachyceny kyslíkovými ionty s poruchou příměsných iontů. V případě, kdy O- stabilizují ionty Nb5+ nebo Li+, jsou teplotně stabilní až do 160-170 K. Studium kinetických charakteristik samozachycených děr svědčí o tom, že díry opouštějí kyslíkové ionty tepelně asistovaným tunelovancím mechanizmem dvěma mírně se odlišujícími kanály. Odpovídající ionizační energie je E=90 meV a pre-exponenciální faktor je asi 10^5 s-1. Ve světle scintilačních a termoluminiscenčních charakteristik CdWO4 jsou diskutovány termální stabilita a kinetické charakteristiky zachycených děr. (cs)
- The self-trapping of holes at oxygen anions was studied by electron spin resonance in UV irradiated CdWO4 crystals. It was found that the self-trapped hole is either delocalized in the space between two energetically equivalent nearest neighbor oxygen ions or tunnels between them. When the temperature increases above 40-50 K the holes are thermally liberated and can be retrapped by oxygen ions perturbed by impurity ions. In case of the Nb5+ or Li+ stabilizing impurities the O- centers are thermally stable up to 160-170 K. Study of kinetic characteristics of the self-trapped holes suggests that holes leave oxygen ions by thermally assisted tunneling mechanism via two slightly different channels. Corresponding ionization energy is E=90 meV and pre-exponential factors are about 10^5 s-1. Thermal stability and kinetic characteristics of the trapped holes are discussed in light of the scintillation and thermoluminescence characteristics of CdWO4.
