Synthesis of Alkali Metal Doped Tungsten Bronze Nanoparticles by Using Oleylamine as Surfactant and Solvent |
초록 |
We provide the synthesis of quaternary tungsten bronzes doped with sodium and cesium via a low-cost sol-gel process employing surfactants. The nanocrystal of CsxNayWO3 was prepared using the sol-gel process with oleylamine as surfactant and solvent. Through transmission electron microscopy (TEM), we confirmed that synthesized tungsten bronze nanoparticles capped with oleylamine have a diameter in the range of 10–30 nm. The carbon chain of surfactant made tungsten bronze nanoparticles well-dispersed in non-polar solvent(toluene), showing 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. |
