Abstract

Raman spectra, measured on silica and silicophosphate aerogels in the range of 5 to 70 cm−1 , revealed a “particle band” that arises from the discrete particulate character of the gels at very small size scales. TEM measurements of the nanoscale structure in the gels correlate with the location of the particle band maximum.
