Synthesis, X-ray Single-Crystal Structural Characterization, and Thermal Analysis of Bis(O-alkylxanthato)Cd(II) and Bis(O-alkylxanthato)Zn(II) Complexes Used as Precursors for Cadmium and Zinc Sulfide Thin Films.

This work investigates tuning of the molecular structure of a series of O-alkylxanthato zinc and cadmium precursor complexes to enhance production of ZnS and CdS materials. The structures of several bis(O-alkylxanthato) cadmium(II) complexes (-) and bis(O-alkyl xanthato)zinc(II) complexes ( and ) are reported based on single crystal X-ray diffraction data. CdS and ZnS films were produced by the spin-coating of these metal complexes followed by their thermal decomposition to the corresponding metal sulfides.

The deposition of thin films of cadmium zinc sulfide Cd Zn S at 250 °C from spin-coated xanthato complexes: a potential route to window layers for photovoltaic cells.

Thin films of Cd Zn S (CZS) were prepared by a novel spin coating/melt method from cadmium ethylxanthato [Cd(CHOCS)] and zinc ethylxanthato [Zn(CHOCS)] in ratios of 0-0.15 and of 1. A solution of the precursor(s) in THF was spin coated onto a glass substrate and then heated at 250 °C for 1 h under N.
