SBIR Phase I: CdSe Nanoparticle/Metal-Organic Inks for Printable Electronics

这个小企业创新研究（SBIR）第一阶段项目将开发一种低温常压沉积工艺，用于电子领域的金属硫族化物纳米材料。该工艺将使用含有CdSe纳米粒子的混合墨水，在非水溶剂中混合活性分散剂。反应性分散剂是一种金属有机分子，在环境温度下会与CdSe纳米颗粒强烈配合形成悬浮液。在喷雾沉积过程中，反应分散剂会在较低的温度下热转化为CdSe和副产物。因此，这种方法将允许在温度敏感基板上印刷CdSe薄膜材料，例如那些对柔性显示器感兴趣的基板。该项目的商业应用包括大面积平板显示器、薄膜晶体管制造、喷射沉积油墨配方和印刷电子材料。

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. The commercial applications of this project include large area flat panel displays, thin film transistor fabrication, jet deposition ink formulations and printed electronic materials.
