ynthesis of functional nanoparticles and their applications
for smart window will be introduced. Various kinds of
nanomaterials and their composites were successfully
synthesized by solvothermal process. Thin films on glass
substrate were fabricated by doctor blade method using
nanoparticles as starting materials. The mixed valence state

possessed excellent IR light shielding properties. In summer
days, the mixed valence state tungsten based IR-shielding smart
coating can block harmful UV light and most of the NIR lights with
heat effect and keep cooler indoors, also transmit visible light.
While, in winter days, the turnaround smart coating reduces heat
loss from indoors, transmit visible light effectively. It is obvious
that these materials have potential applications for the heat ray
shielding and indoor energy saving effect. On the other hand, VO
2
monoclinic based nanoparticles possessed excellent and smart
thermochromic property, possessed heat ray shielding effect in
summer and heating effect of indoors in winter. The VO
2
based
materials show higher energy saving effect than those of normal
IR shielding materials. Also, multifunctionality of thin films was
successfully realized by fabricating the composites with various
functional components. Not only UV/IR shielding property, but
also environment purification and self-cleaning functions can
be expected, indicating their great potential as novel housing
materials. The design of composites and thin films structure
might result in property improvement of particle applications for
smart windows.
