Paper Abstract

The lifetime of the near-infrared emission of oxazine-1 and 1,1',3,3,3',3'- hexamethylindotrycarbocyanine iodide (HITC) into gel-glasses prepared from TMOS or TEOS are studied by variable frequency phase and modulation data. Analysis of the lifetime by a fitting procedure to an assumed model revealed two lifetimes with a low value of the reduced chi-squared for the studied doped gel-glasses. The longer lifetime is attributed to the adsorbed species, while the shorter to species which are affected by the remaining solvent in the pores. The contributions of these species to the total fluroescence are also resolved.
