Controlled X-Ray Induced Gold Nanoparticles Deposition

Abstract. This paper outlines new approaches for utilizing X-rays for gold nanoparticles deposition by performing Surface Photochemistry Induced by X-ray Irradiation (SPIXI). High-energy synchrotron radiation was used to induce the deposition of gold nanoparticles from a gold-salt solution onto different surfaces. By controlling the deposition parameters (dose, solution, surfactants, and stabilizer polymer concentrations), the distribution and average size of the nanoparticles can be influenced. The distribution of the deposited particle heights and diameters at low doses suggests there is a mechanism of growth of the particles after nucleation on the surface.
