Abstract
Inhomogeneously broadened luminescence spectra of Cr3+, Eu3+ and Pr3ions in sol-gel-grown monolithic highly porous Y-Al2O3 were observed. In FLN and HB experiments, the interaction of ions with the size-reson ant terahertz acoustic vibrations of crystalline nanoparticles which f orm the porous network was studied. The incorporation of Eu3+ and Pr3 into alpha-Al2O3 (corundum) lattice is demonstrated in annealed (T > 1200 degrees C) sol-gel-prepared samples.
