I found the Chart for types of Phosphors and the corresponding CIE graph locations.

I had one form Thomas Electronics they sent me to show what phosphors they had stock. They also said they could make them to order. But that was 4 years ago.

Guys

One of the Electrohome engineers sent me a chart like that years ago, listing colors and decay times. There was an orange phosphor with a decay of several seconds, for a radar tube, or maybe traffic lights Smile
