In this research we study optical absorption and morphology of silver films prepared with a sputtering method. Silver granular films are obtained on a glass substrate for films with thickness smaller than about 60 Å. Superficial silver clusters of around 100 nm in diameter are clearly seen in the atomic force micrographs. The absorption of these samples are characterized by plasmon excitation in the 450-650 nm spectral range, which differs from the known excitation of silver nanoparticles fabricated by different techniques. The optical absorption of silver granular films depend on sputtering conditions like substrate temperature or deposition rate and correlates with the surface morphology.

Mechanical And Electrical Properties

TiC particles/Ag composite films were successfully prepared through co-electrodeposition, using the Ag plating solutions with minor addition of TiC particles, followed by heat treatment in vacuum. The X-ray diffractometer (XRD), scanning electron microscope (SEM), nanoindentation tester and four-point probes were used to characterize phase composition, morphologies, mechanical properties and electrical properties of as-fabricated films, respectively. Experimental results show that only TiC and Ag phases are identified for the TiC particles/Ag composite films. TiC particles are incorporated tightly and evenly on the surface of the composite films without obvious agglomeration. TiC particles/Ag composite films maintain good electrical conductivity. Meanwhile, compared to pure silver film without the addition of TiC particles, the indentation hardness ([Formula: see text]) of the TiC/Ag composite film electrodeposited from the plating bath containing 6[Formula: see text]g/L of TiC particles can be improved from 600 [Formula: see text] to 11,000 [Formula: see text].
