We have investigated the evolution of the size and the morphology of A
u nanoparticles fabricated by rf magnetron sputtering techniques at ro
om temperature as a function of sputtering gas pressure, p; rf, input
power, L; and sputtering rime, t. For 60 less than or equal to p less
than or equal to 300 mTorr, Au nanoparticles were deposited. For 60 le
ss than or equal to p less than or equal to 250 mTorr, the particle si
ze increased with increasing Land extending t. On increasing L and t f
urther, film formation occurred. When p = 300 mTorr, nanoparticles for
med at L = 200 W.
