摘要：

The monolithic polycrystalline small-grain corundum alpha-Al2O3 doped with trivalent rare earth ions RE3+ (Eu3+, Er3+, Pr3+) was produced for the first time using the sol-gel technology. The fluorescence and absorption spectra of these materials were studied which exhibit the sets of narrow lines belonging to f-f transitions between RE3+ states. It was shown that Eu3+ and Er3+ ions form in corundum lattice the single dominating type of regular centers. The energy scheme of Stark sublevels for ground and excited states of dominating Eu3+ and Er3+ centers in corundum was determined.
