“Mechanical stresses in Al2O3:Cr monocrystals irradiated with xenon high-energy ions”

24.05.2018 – FLNR CAP Scientific Seminar “Mechanical stresses in Al₂O₃:Cr monocrystals irradiated with xenon high-energy ions”, 15-20, Flerov Lab Conference Hall. 

Speaker: Komarova D.A., ESNT NRTPU. (On Master thesis) 

The results of piezospectroscopic analysis of the profile of mechanical stresses in Al₂O₃:Cr monocrystals irradiated with 1,2MeV/n xenon ions are presented. Method of sample preparation for measurement of spectra of photostimulated luminescence of laser confocal scanning microscope in cross-section geometry is given. It’s shown that stresses profile spacial resolution in this method is 1,0 mkm which is much higher (>=3 mkm) of standard measurements resolution with focus motion in sample depth.
