What is the best metal to be used with a Xe-flash lamp (200-2000nm) for photoelectric effect in LAr (e.g. Au no oxidation, but high work function)?

I am currently using a Xe-flash lamp (200-2000 nm spectrum) to extract electrons from a gold plate (~100 nm deposition). Gold has a work function of around 5.1 eV (~245 nm) and does not oxidise....
