Clear gels have been made from TEOS and the amino functional silane under acid-catalyzed conditions and light scattering of the gels has been related to pH and the concentration of fluoride ions in the sol as well as the amount of the amino silane used. The authors have succeeded in preparing a series of gels containing Ni{sup 2+} or Cu{sup 2+} ions immobilized by chelation either before or after the gel formation. Aerogels made from these gels in particular, doped by the method of impregnation, have had a homogeneous microstructure on the scale of only a few nanometers.
