Description
  • A study of the decay kinetics of YAG:Ce single crystal scintillators for SEM is presented in this paper. The principal quantities of image quality in SEM are contrast, spatial resolution, and noise. However, to quantify the overall performance of an imaging system, the detective quantum efficiency (DQE) is a better tool as it includes both the modulation transfer function and the noise power spectrum. This means that for a detector to have high DQE, it should possess not only high efficiency and low noise, but also good kinetic properties. Utilizing of the cathodoluminescence decay results, a schematic kinetic model of radiative and nonradiative transitions in the YAG:Ce single crystals is presented.

  • V této práci je presentováno studium kinetiky doznívání monokrystalických scintilátorů YAG:Ce pro SEM. Základní veličiny určující kvalitu obrazu v SEM jsou kontrast, prostorové rozlišení a šum. Nicméně pro vyčíslení celkové kvality zobrazovacího systému je lepší detekční kvantová účinnost (DQE), neboť zahrnuje jak funkci přenosu modulace tak spektrum šumu. Z toho vyplývá, že detektor, který má mít vysokou DQE, by měl mít nejen vysokou účinnost a nízký šum, ale také dobré kinetické vlastnosti. S využitím výsledů doznívání katodoluminiscence je presentován schematický kinetický model zářivých a nezářivých přechodů v monokrystalech YAG:Ce. (cs)
