THERMAL SENSOR-BASED ON LUMINESCENCE OF RU(BPY)(2-GEL GLASSES()(3) ENTRAPPED IN SOL)

Samples of glasses containing Ru(bpy)(3)(2+) (bpy-2,2'-bipyridine) hav e been prepared by the sol-gel method. Electronic absorption and emiss ion spectra of the entrapped ruthenium complex have been obtained in v arious temperatures ranging from 15 to 340 K. Incorporation of the com plex in the glass results in the blue shift of the emission maximum. T he obtained glass samples containing Ru(bpy)(3)(2+) have been utilized as temperature sensors via relating the phosphorescence intensity to temperature. The experimental setup of the thermosensor (optode) is di scussed.
