Popis:	Optical sensors suitable for monitoring of O2 in water medium were prepared by immobilization of metallo-organic complexes in xerogels created by sol-gel technique and applied to optical fibre tip or glass slides by dipping. Tris (1,10-phenanthroline)ruthenium (II) chloride was immobilized on the tip of optical fibre. The fluorescence spectra of the complex were sensitive to O2 in water solution. The sensitivity of absorption spectra of bis(histidinato)cobalt (II) to O2 and pH was examinated both in the solution of precursors of silica sol-gel glasses and in the complex-containing coating of glass slides.
