Abstract
Nanoleaf-like Bi 2S 3 thin films were deposited on indium tin oxide (ITO) glass using Bi(NO 3) 3 and Na 2S 2O 3 as precursors by a cathodic electrodeposition process. The as-deposited thin films were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM) and photoluminescence spectrum (PL). The influence of precursor solution mole concentration ratios [Bi(NO 3) 3]/[Na 2S 2O 3] on the phase compositions, morphologies and photoluminescence properties of the obtained thin films were investigated. Results show that a uniform Bi 2S 3 thin film with nanoleaf structure can be obtained with the precursor solution concentration ratio [Bi(NO 3) 3]/[Na 2S 2O 3] = 1:7. The as-prepared thin films exhibit blue-green photoluminescence properties under ultraviolet light excitation. With the increase of concentration ratios [Bi(NO 3) 3]/[Na 2S 2O 3] in the deposition solution, the crystallizations and PL properties of Bi 2S 3 thin films are obviously improved.
