From bare metal powders to colloidally stable TCO dispersions and transparent nanoporous conducting metal oxide thin films

Abstract

A simple, green, robust, widely applicable, multi‐gram and cost‐effective ‘one‐pot’ synthesis of aqueous dispersions of colloidally stable 3–6 nm TCO NPs using bare metal powder precursors is described, and their utilization for making TCO high surface area nanoporous films is also demonstrated, which speaks well for their usage in a wide range of possible processes and devices.
