摘要
Sol-gel produced nanocrystalline highly porous transparent gamma-Al2O3 doped with RE and TM ions and alpha-Al2O3 ceramics, produced by its annealing, were studied with selective laser spectroscopy techniques. The site-selective spectroscopy of RE3+ ions in alpha-Al2O3 reveals that these ions form centers in corundum with one dominating type. The FLN studies of homogeneous line widths of 5D(0)-F-7(0.1) transition in gamma- and alpha-Al2O3 extend the low-temperature hole-burning data (Feofilov et al., Phys. Rev. B 54 (1996) 3690). It is shown that Mn4+ -doped Al2O3 is potentially effective photochemical hole-burning material and self-gated persistent hole-burning in alpha-Al2O3:Mn was demonstrated.
