Abstract

The research objective of this project was the spray deposition of CdSe films using a nanoparticle CdSe suspension as the precursor ink. This ink consisted of CdSe nanoparticles (nano-CdSe) mixed with a “reactive dispersant” in a non-aqueous solvent. The reactive dispersant, a metal-organic molecule, served two purposes; (1) to form a dispersed CdSe suspension at room temperature, and (2) to thermally “unzip” giving CdSe and a byproduct. The CdSe thereby formed could be deposited at the grain boundaries and serve to physically and electrically connect the CdSe nanoparticles at moderate, plastic-compatible temperatures. If electronics-grade CdSe layers could be produced at low deposition temperatures, this approach may be applicable to printed CdSe-based thin film field-effect transistors (TFTs) on flexible substrates.

While the shape of the TGA curves for the crude samples was nearly identical to that of the purified, the total mass loss was much less. This observation might explain the impurities in the TGA residue of the crude materials.Google Scholar
