Popis:	Silicate glasses with additions of cerium and titanium oxides are studied. Such glasses are of interest for manufacturing electric lights for automobile headlights and heat-stable light filters. It is established that the characteristic yellow-orange color is due to the formation chromophoric centers containing products from the interaction of cerium and titanium oxides. It is proposed on the basis of optical transmission and photoluminescence measurements as well as XPES data obtained for the composition used in light filters that titanium and cerium are present predominately as the ions Ti4+, Ce3+, and Ce4+.
