Multidisciplinary research using charged particle beams


Radiolysis is a particularly suitable method to form metal nanoparticles in solution. The interaction of high-energy radiation with a solution of metal ions induces ionization and excitation of the solvent (water), and leads to the formation of radiolytic molecular and radical species throughout the solution. The produced solvated electrons eaq- and hydrogen atom H.  are strong reducing agents capable to reduce metal ions to lower valences and finally to metal atoms.

Our experiments were carried out on two different EB accelerators: ALIN-10 (6.23 MeV and 200 kGy/min) and ALID-7  (5 MeV, 7 kGy/s). To control size, shape, narrow distribution and yield of NP’s formation different reaction conditions are used: dose rate, absorbed dose, the initial concentration of precursors. The use of EB irradiation is a useful method to generate stable silver NP without the interference of inherent impurities generated from chemical reactions
