摘要: Abstract Fluorine-doped tin dioxide (FTO) films were elaborated from a new Sn(IV) molecular precursor, the tert amyloxyfluorodipentan-2,4-dionatotin(IV) complex, to be used via sol–gel route. Upon controlled hydrolysis in acetonitrile, fluorinated polystannoxane was formed as stable xerosol, which characterized by multinuclear magnetic resonance and Mossbauer spectroscopies, elemental analysis, thermogravimetry coupled mass spectrometry. This xerosol further dissolved acetonitrile for depositing highly transparent spin-coating spray pyrolysis techniques. Film composition determined X-ray photoelectron spectroscopy, electron probe microanalysis energy dispersive analysis. The F/Sn atomic ratio 3% spin-coated 10% sprayed films. A noticeable amount of carbon (C/Sn #10 at.%) detected whatever deposition technique. In every case, film resistivity found larger than one obtained separate fluorine precursors. result attributed excess content oxide layers relieved xerosol.
