摘要：
Greenockite (CdS) nanostructured thin films are deposited on soda and FTO conducting glass substrates by aerosol-assisted (AA)CVD using a single-source precursor bis-(N,N-dicylcohexyldithiocarbamato)(pyridine)cadmium(II), Cd[S2CNCy2]2.py (1), in pyridine, toluene, and THF solutions in the temperature range 350450?degrees C. The precursor 1, characterized by physicochemical methods, undergoes facile thermal decomposition at 350?degrees C to give a stable residual mass of CdS. The thin films deposited from pyridine solution, and characterized by X-ray diffraction (XRD), UV-vis spectroscopy, field-emission scanning electron microscopy (FESEM), and energy dispersive X-ray (EDX) techniques, exhibit a band gap of 2.4?eV and a photocurrent density of 1.3?mA?cm-2 at 0.4?V versus Ag/AgCl/3M KCl, suggesting their suitability for application in photoelectrochemical (PEC) cells.
