I~rsrir~rrc of Cltcnk:r_~ . The Hebrew Un.5 ersir> 0-f Jmrsn~em, Je~~sale~n 919Od. Israel Kcccived 28 April 19S3 I'luorescenc~ of rare earth (RE) ions arising from f-f transitions in Pr3+, Eu3+, Tb3+, Dy3+. Ho3+, Er3+ and Tm"* was obsened from the ions adsorbed on porous 1') car glass or on pressed discs of fumed silica. The non-radiative relaxations of the evited states \cre depressed as ;1 result of a stron_c chemical bond between the ions and silica acting ass ligand.
