Abstract
Persistent spectral hole burning (PSHB) has been observed at 110 K in EU(3+) exchanged Nai beta'-alumina crystals. This is the highest burni ng temperature for PSHB in EU(3+) doped materials. It is found that th e long lived holes at high temperature are caused by light-induced loc al motion of ions surrounding the EU(3+) ions. The results both of hol e relaxation and temperature cycling measurements can be well interpre ted by a hopping model with a Gaussian distributed barrier height.
