Xerogel layers based on the tetraethoxysilane and methyltriethoxysilane were applied into cappilaries fibers and microstructure silica fibres. Sensitivity toward vapous of water and toluene in mixture with nitrogen was determinated from spectral responses in the range 1100-1800nm. Experimental results were compared with layers applied on silica fibers.
Xerogelové vrstvy na bázi tetraexthoxysilanu a methyltriethoxysilanu byly naneseny do kapilárních a mikrostrukturních křemenných vláken. Ze spektrálních měřeních v oblasti 1100-1800nm byla určena citlivost vrstev vůči parám vody a toluenu. Výsledky byly porovnány s vrstvami nanesenými na křemenná vlákna.
