[Vo]:Co-deposition question about visible light emission.

[Abd ul-Rahman Lomax]

There is some nice video of a co-dep cathode under observation by a 
infrared camera, showing hot spots twinkling, by the SPAWAR group. 
That group also has some nice photos showing what certainly looks 
like little volcanos of melted palladium, which would have to be 
awfully hot, palladium melts at 
1828<http://en.wikipedia.org/wiki/Kelvin>K, and boils at 
3236<http://en.wikipedia.org/wiki/Kelvin>K . Incandescence in the 
visible begins at about 670K, according to my favorite reference, 
Wikipedia. There should be visible light. Has anyone looked for it, 
particularly with a microscope?
