Abstract:
The invention relates to colloidal films of metal oxide particles and organic acids, wherein the organic acid contains at least two carboxylic acid groups. These films can be used in many applications, including light-emitting devices and photovoltaic cells. When added to the metal oxide particles, the organic acids provide good mechanical strength and prevent the colloidal films from delaminating and flaking, while simultaneously avoiding the need for high temperature sintering.
