摘要:
Solid solutions of the CdS-ZnS system deposited as polycrystalline films by aerosol pyrolysis from aqueous solutions of cadmium and zinc thiourea complexes have been studied. The phase composition and solid-phase solubility are dictated by the nature of initial complexes. From solutions of [M(thio)(2)(CH3COO)(2)] complexes, sphalerite sulfides are precipitated, which form a continuous solid solution s-Cd1-x Zn (x) S, whereas the use of the [M(thio)(2)Cl-2] precursor leads to crystallization of the wurtzite w-Cd1-x Zn (x) S solid solution based on CdS (the homogeneity range 0-20 mol % ZnS) and the s-Cd1-x Zn (x) S solid solution based on zinc sulfide (50-100 mol % ZnS). The structure of the solid phase in the sulfide system is attributed to the specific features of the stereochemistry of complex precursors.
