The structure of heat-treated sol-gel-made SiO 2 samples containing copper or iron in various amounts was studied using Raman spectroscopy and x-ray diffraction. The treatments were in air in the temperature range 200-800 • C. Copper and iron concentrations were in the range 7-55 wt%. It was found t
