Аннотация
In this paper we report the synthesis and characterization of TiO2
nanocrystal dispersed into a porous Vycor glass. We have obtained very
small TiO2 nanocrystals in the anatase form. The nanocrystal size is
controlled via the mass increment only thus preventing the growth
through the coalescence process. The nanocrystal size was monitored
through transmission electron microscope and Raman scattering. The
coalescence control is attributed due to the obtention of nanocrystals
dispersed into the host and to the terminal bonds present in the porous
which act as an anchor thus resulting in a low diffusion of the
nanocrystals through the porous network.
