Swift heavy ion irradiation of Pt nanocrystals: I. shape transformation and dissolution

Giulian, Raquel; Araujo, Leandro; Kluth, Patrick; Sprouster, David; Schnohr, Claudia; Byrne, Aidan; Ridgway, Mark C


We report on the effects of swift heavy ion irradiation of embedded Pt nanocrystals (NCs), which change from spheres to prolate spheroids to rods upon irradiation. Using a broad range of ion irradiation energies and NC mean sizes we demonstrate that the elongation and dissolution processes are energy and size dependent, attaining comparable levels of shape transformation and dissolution upon a given energy density deposited in the matrix. The NC shape transformation remains operative despite...[Show more]
