Synthesis and the properties of vanadium dioxide nanocrystals in porous silicate glasses

Impedancemetry of Ag-=SUB=-2-=/SUB=-S nanocrystallites embedded in nanoporous glasses

“…The procedure of " incremental building", providing pores filling with Ag 2 S nanocrystallites, was used for NPG plates with through porosity. For that silver chlorides/nitrates were used with their further processing in hydrogen sulphide vapors with removal of the formed acid [8].…”

Nanothermochromics: Calculations for VO2 nanoparticles in dielectric hosts show much improved luminous transmittance and solar energy transmittance modulation

“…In fact, experimental work on such nanoparticles has soared during recent years. We first note that VO 2 nanoparticles occluded in a silica matrix have been fabricated via reduction in a glass containing V 2 O 5 by use of hydrogen, 53,54 ion implantation of vanadium and oxygen ions in a silica host, 27,28 and sol-gel deposition. 55 Very well controlled nanostructures have been made by introduction of VO 2 into the voids of synthetic opal comprised of SiO 2 nanospheres.…”

Synthesis and optical properties of hybrid “plasmon-exciton” nanostructures based on Ag-AgI in nanoporous silica glass

“…NPGs are optically transparent, heat resistant, and the NPG plate thickness can reach 10 mm, which allows the development of bulk nanocomposite samples. In fact, the nanopore in glass can be considered as a nanoreac tor in which multistage physicochemical reactions, heat treatment, and irradiation of isolated nanoobjects can be performed (see, e.g., [22]). After completing the synthesis, nanoparticles can be conserved in pores by filling them with polymer or by pore "collapse" upon high temperature heating.…”
