Abstract

A variety of reactions employing organometallic precursors have been explored for the synthesis of ZnS. One of the most successful routes involves the reaction of [EtZn(SButS)]5 with H2S at ambient or sub-ambient temperature to yield a precipitate which is subsequently heated under flowing H2S at 500°C to yield a mixture of sub-micron particles and single-crystal ZnS whiskers. Transmission electron micrographs of the [EtZn(SBut)]5 products indicate that the ZnS morphology is critically dependent upon the rate of H2S reaction. Corresponding x-ray/ electron diffraction, electron microscopy, elemental analysis, NMR and infrared spectroscopies have been conducted. A summary of the chemical methods, product characterization results, and proposed synthesis mechanisms will be presented.
