Schematic diagram of particles synthesized in X-ray-radiolysis-induced photochemical reaction in a liquid and near the surface of a substrate dipped in solution. (a) Route 1 shows the series of particle nucleation, growth, ripening and aggregation induced by the X-ray-radiolysis-induced photochemical reaction in a liquid solution. After the particle ripening is partially completed, it adheres to the surface of the substrate. (b) Route 2 shows that a secondary electron induced from the substrate by X-ray irradiation contributes to the reduction of metallic ions and precedes the nucleation and growth of particles on the surface of substrate. |
