Native aerogels

Figure 8.7 Top Effect of density on the optical bandgap for aerogels prepared from naked CdSe nanopaiticles and CdSe-ZnS core-shell nanoparticles. Bottom CdSe-ZnS core-shell aerogel and xerogel monohths under normal (left) and UV (right) illumination. The native aerogel and xerogel are orange under normal hght and fluorescent green under UV stimulation.

Figure 14.5. Typical SEM and N2 sorption data for the RF-MOx systems in the native aerogel, xerogel, and X-aerogel forms. Case shown the RF-CoO system. Open circles, adsorption dark circles, desorption. Insets BJH curves from the desorption branches of the isotherms.

Figure 14.7. Typical XRD and EDAX data as a function of pyrolysis temperature (under Ar) for the smeltable RF-MOx systems in the native aerogel (top), xerogel (middle), and X-aerogel (bottom) forms. Case shown RF-SnO to.
