Low-hydroxyl organically modified silicates (ORMOSILS) were fabricated by a nonhydrolytic reaction between methyl-modified silicon halides and tertiary butyl alcohol under controlled atmosphere. The gels were characterized by DTA and TGA., FTIR, {sup 1}H NMR and {sup 29}Si NMR. The solutions were doped with anhydrous ErI{sub 3}, which was dissolved in the sol prior to gelation. Er{sup 3+} luminescence in the gels was observed at 570 nm under excitation at 488 nm.
