GeO 2 gel and gels in the SiO 2 ‐GeO 2 system synthesized by the hydrolytic polycondensation of metal alkoxides have been studied by infrared and Raman spectroscoptic techniques. The molecular structures, hydroxyl contents, and crystallinity of gels and gel‐glasses in relation to the thermal history and GeO 2 concentration were investigated. The binary compositions having up to 70 mol% GeO 2 were examined.
