High rate laser deposition of conductive copper microstructures from deep eutectic solvents.

In this communication, the phenomenon of the laser chemical deposition of copper using deep eutectic solvents (DESs) on a dielectric substrate has been shown for the first time. The use of eutectic solvents made it possible to greatly simplify the procedure of metal deposition and increase the deposition rate by more than 150 times compared to the use of aqueous solutions.
