ABSTRACT:
A method of preparing films having the formula A.sup.IIB B.sup.VIA wherein A.sup.IIB is a group IIB metal and B.sup.VIA is a chalcogenide by the photolysis or low temperature thermolysis of an organo-metallic compound containing the targeted A.sup.IIB B.sup.VIA elements is provided. Organo-metallic compounds utilized in the method are of the general formulas R-X-M-X-R', R-M-X-M-R', R-M-X-R', R-M-CH.sub.2 -X-R', R-M-X-X-R' wherein R and R' are hydrogen, an alkyl, an aryl or an organic radical containing a heteroatom, M is a group IIB metal and X is a chalcogenide. Photolysis is carried out with an ultraviolet, visible or infrared light source. The films are useful in the manufacture of semiconductor elements and optical coatings.
