Radio-Luminescence of Defects and Impurity Ions in Magnesium Aluminates Spinel Crystals

Abstract:

Article Preview

The investigations of radio-luminescence (RL) in magnesium aluminates spinel crystals at variation of the time, intensity of X-irradiation and temperature of sample were provided. There were registered three prominent RL bands related to electron-hole recombination process at anti-site defects, emission of Mn2+-ions and emission of Cr3+-ions. The kinetics of the growth of indicated RL emissions show the competing processes of the capture of free charge carriers generated at irradiation by intrinsic defects and impurity ions.
