Antimony tin oxide

Hi,
Found this online.
"ATO (Alfa-Aesar) nanoparticles were redispersed in water using
tetramethylammonium hydroxide (TMAH) as a dispersing agent. The ATO powder was
massed and combined with 10 wt.% TMAH solution (Sigma-Aldrich) in a ratio of 0.1823
μ
L of TMAH solution per mg of ATO [6]. Water was added to adjust the ATO dispersion
concentration, and the dispersion was sonicated for 10 minutes and stirred until
deposition. Dispersions of 0.1 wt.% and 5 wt.% were made. "

I have managed to source ATO nanoparticles, resembles a blue powder but obviously a lot finer.

Was hoping to make some transparent conductive oxide for EL use, any ideas which glue might work?
Had some success with tyre cement but this is expensive and the fumes are noxious.

Would an epoxy work for this perhaps?
thanks!

From memory conductive glues require a very high solvent fraction, so that the conductive particles end up touching when the solvent evaporates.

Thanks, will try this out later.

Also relevant, folks have used ATO + tyre cement as an interface to superconductors as despite the high resistance it is "nicer" to the ceramic and the solvent being nonaqueous forms a robust and stable impermeable surface for silvering etc.

EDIT: Used Sellotape to make a version of conductive film, a useful tip is to read the FAQ in Dupont Luxprint (tm) and use Sellotape, glass and a metal rod to get an even layer.
When the sticky label is placed onto this and tapped it forms a nice even layer and traps the ATO.

This approach also works well with EL powder or reprocessed glow powder recovered from Halloween face paint paste.
