Chemical bath deposition technique at room temperature proved to be efficient in synthetizing elemental silver clusters on Silver (I, II, III) oxide clathrate films, Ag0/Ag708HCO3.The set of samples was prepared for 30, 60, 90 and 120 minutes.All films exhibited a yellowish-brown color and presented good adherence to the corning glass substrate.The direct band gaps values were 3.77 to 3.82 eV.A cubic crystallographic structure was determined with the usage of TEM; while SEM was used for the observation of their morphology which showed a very homogenous flat background with a distribution of metallic silver clusters with irregular shape was growing.
