Abstract

We report the successful fabrication of layers of functionalized nanoparticles using a novel infrared, laser-based deposition technique. A frozen suspension of nanoparticles was ablated with a laser tuned to a vibrational mode of the solvent, resulting in the disruption of the matrix and ejection of the nanoparticles. The solvent was pumped away and the nanoparticles collected by a receiving substrate in a conformal process. Photoluminescence measurements of nanoparticles containing two common dyes showed no significant change to the emission properties of either dye, suggesting that no damage occurred during the laser ablation process. The process is generally applicable to particles of various sizes, shapes, and chemistries provided that an appropriate solvent is chosen. Deposition through shadow masks turned out to be straightforward using this technique, suggesting its potential utility in preparing designer sensor structures using functionalized nanoparticles.
