INVESTIGATION AND OPTICAL EVALUATION OF PRECURSORS FOR THE PHOTODEPOSITION OF NANOSIZED ZnS AMORPHOUS THIN FILMS

Thin amorphous nanostructured ZnS films have been photochemically obtained by means of direct UV radiation (X= 254 nm) of the complex Zn [ (CH3)2CHCH2OCS2 ]2 deposited on Si(100) and on ITO glass through the spin-coating technique. The UV photolysis of thin films of Zinc Xanthate complex results in...
