This Small Business Innovation Research (SBIR) Phase I project will develop a low-temperature, atmospheric-pressure deposition process for metal chalcogenide nanomaterials in electronics. This process will use a hybrid ink containing CdSe nanoparticles mixed with a reactive dispersant in a non-aqueous solvent. The reactive dispersant, a metal-organic molecule, will strongly coordinate to CdSe nanoparticles to form a suspension at ambient temperatures. During spray deposition, this reactive dispersant will thermally transform into CdSe and byproducts at relatively low-temperature. As a consequence, this approach will allow printed CdSe thin film materials on temperature-sensitive substrates such as those of interest in flexible displays.<br/><br/>The commercial applications of this project include large area flat panel displays, thin film transistor fabrication, jet deposition ink formulations and printed electronic materials.
