Abstract

Thin film of bundled cadmium sulfide nanotubes (CdS NTs) have been successfully prepared on indium tin oxide (ITO) substrate. CdS nanoparticles (NPs) are agglemerated and aggregated to form the tube wall of the CdS NT structure which possesses the advantages of large surface area and surface-interface state for generating strong and stable electrochemiluminescence (ECL) signal. The ECL intensity of the bundled CdS NTs thin film is highly sensitive to the flow rate of electrolyte. The CdS NTs produce the highest ECL intensity for an electrolyte of pH 11.8 and 1.27 mL·min ^-1. The possible mechanisms of this flow sensing characteristic are discussed. It is anticipated that this bundled CdS NTs film has potential for applications in measuring the flow rate of solutions or as a pressure sensing element.
