A simple chemical method for the deposition of highly crystallized SrMoO4 films

Well-crystallized SrMoO4 films have been prepared directly on molybdenum substrates in an alkaline aqueous solution containing strontium ions by a simple chemical reaction at room temperature. In order to keep the free growth of SrMoO4 crystals in solutions, a mild oxidizing agent, NaClO, plays an important role in the formation of desired film. XRD and SEM results indicate that the films have single phase and uniform surfaces. The film shows a broad emission band centered at 487 nm with the excitation light of 240 nm, 250 nm and 270 nm at room temperature, respectively.
