Abstract
The results of a study of a new class of User solid-liquid medium (SLM) based on dye solution impregnated microporous glass (MPG) are presented. MPG is a pure: quartz glass with a through porous 10- 1000-Å diameter depending on the technology. Dye solutions penetrating the glass distribute homogeneously in its volume. Thus, there are three types of active center with different spectral fluorescent characteristics: the dye molecule is closely sorbed on the porous surface, the dye molecule interacts with the surface by van der Waals forces, and the molecule is packed in solvent with no interactions.
