摘要: Silica-silver core-shell composite particles with uniform thin silver layers were successfully synthesized by a facile and one-step ultrasonic electrodeposition method. By electrolysis of the slurry consisting preformed silica spheres perchlorate without any additives, homogenous can be prepared. The average size single crystals in is about 12 nm thickness layer 14{+-}2 nm. Moreover, continuity Ag distribution, surface roughness are controllable adjusting current density (I), concentration electrolyte (C) reaction time (t). Optical properties different content also investigated. - Graphical abstract: prepared controllable.
