Abstract

A luminescent compound, comprising a phosphor group or groups and an alkylalkoxysilane, and a luminescent composition comprising such luminescent compound and a radioactive substance to provide a source of exciting radiation for the luminescent compound in the composition. The present invention further comprises a method for rendering siliceous surfaces luminescent comprising applying the compound or composition to the surface and reacting the compound or composition with water after the compound or composition has migrated into the surface to hydrolyze the compound or composition. The present invention further comprises a luminescent structure having a siliceous surface incorporating the products of the reaction between the surface, water and the compound or composition of the present invention.

A method for rendering a siliceous surface luminescent comprising:

applying to the surface an effective amount of a luminescent compound having the formula:
##STR7## where R.sub.1 is a phosphor group;
where R.sub.2 is an alkyl group containing from 1 to about 8 carbon atoms, a hydroxyalkyl group, or an alkoxyalkyl group;
and where X is a phosphor group, OR.sub.2, or a second binding site for R.sub.1 ;
and
reacting the luminescent compound with an effective amount of water to hydrolyze the luminescent compound after the luminescent compound has migrated into the surface.
