Abstract

We have studied the processes of photocoloration and discoloration in Mn:YAlO3 and relevant crystals. We show the following: (1) The coloration rate in Mn:YAlO3 does not depend on Mn concentration. (2) The effective recombination time of free electrons with Mn5+ ions and deep traps is of the order of ≈0.5 ms. (3) The rate of photocoloration increases with an increase in temperature. (4) The discoloration kinetics in Mn:YAlO3 are strongly nonexponential. At room temperature the effective discoloration time approximates 120 years. (5) At increased temperatures the discoloration kinetics accelerate dramatically. (6) We have grown and characterized Mn:GdAlO3 and Mn:YbAlO3 crystals. The activation energy in these crystals is much larger than that in Mn:YAlO3. This suggests the great potential of MnYbAlO3 and Mn:GdAlO3 in terms of permanent data storage.
