Synthesis of Alkali Metal Doped Tungsten Bronze Nanoparticles for Window Film Application to Shield Near-Infrared Light |
| 초록 |
We report the synthesis of quaternary tungsten bronzes doped with sodium and cesium via a low-cost sol-gel process employing surfactants and their application to composite films. The nanocrystal of CsxNayWO3 was prepared using the sol-gel process with oleylamine as surfactant and solvent. As-synthesized tungsten bronze nanoparticles capped with oleylamine have a diameter in the range of 10–30 nm. Well-dispersed tungsten bronze nanoparticles in non-polar solvent(toluene) show about 97% shielding property of near-infrared(780-2100nm) light as well as about 64% transparency of visible (380-780nm) light. The property of tungsten bronze nanocrystals was highly suitable for solar control filters in automobiles and architectures by applying windows of incoming near-infrared light. |
