Gold nanoparticles prepared with a room-temperature ionic liquid-radiation irradiation method

摘要

Mass production of gold nanoparticles in room-temperature ionic liquids without any stabilizing agents has been achieved with radiation irradiation, i.e., accelerated electron beam and γ-ray.rnMetal nanoparticles, which have a large surface area, surface-plasmon characteristics and so on, are expected to be key materials for further development of science and technology. A great number of articles related to metal nanoparticle syntheses including radiation irradiation methods have been reported to date. Room-temperature ionic liquids (RTILs) are known to be facile solvents for preparing functional materials because of their anomalous physicochemical properties, such as negligible vapor pressure and wide operating temperature range.
