Silver particles growth by pulse electrolysis in acetonitrile solutions

The morphology of silver particles deposited on ITO-glass surface by pulse electrolysis in acetonitrile solutions of AgNO3 has been analyzed. The influences of potential value (E) as well pulse duration (tau(on)) and pause (tau(off)) on the size and geometry of the particles has been discussed. It has been shown that in the range of 0.0 a parts per thousand currency sign E a parts per thousand currency sign -1.5 V at tau(on) = 6 ms and 90 a parts per thousand currency sign tau(off) a parts per thousand currency sign 490 ms formation of silver particles (similar to 20-50 nm) and their agglomeration (similar to 0.2-2 A mu m) take place. The tendency to increase size of the particles in 3D has been observed with the increase of cathode potential. Decreasing of duty cycle leads to more discrete deposited particles.
