Xerogels optical properties

Polysilsesquioxane xerogels Sol-gel processed TiOj, doped by organic compounds having non-linear optical properties CdS TiOj... 

Fig. 12, in which the spectra of thin xerogels corresponding to the micrographs in Fig. 11 have been plotted. It is remarkable that the plasmon band is centred precisely at the same position, regardless of concentration. It has also been shown that for larger gold cores the optical properties are equally preserved during the sol-gel transition. 

This paper summarizes peculiarities of synthesis and optical properties of the microporous xerogel/PAA stmcture highly doped with Er, Tb and Eu. The enhancement of PL emission from these dopants in the structure is discussed.
