Enhanced Near-IR Cutting Performance in the Mixture of Cs x WO3 and Sb:SnO2 Nanoparticles
The Cs

WO3 nanoparticles were synthesized at 800 °C under a reducing ambient, and then milled up to nanoscale by a high-energy ball planetary miller. They showed a single phase, and a mean particle size of 80 nm. The Cs contents (x) in Cs
x
WO3
nanoparticles were optimized to be x = 0.32 to maximize the shielding performance around the wavelength of 1200 nm. To compensate still lower absorption above the wavelength of 1200 nm, they were mixed with Sb-doped SnO2 nanoparticles. Thus we achieved the visible transmittance
of 70% at 540 nm and the near-infrared absorption of 80% at 1000 nm and 94% at 1400 nm.
