P7 long persistence dual phosphor
There is a description of this phosphor technology in Keller's book (...which many on this list now have.)
I've seen an amber phosphor used in the CRT (not a filter only) of an oscilloscope.
I can't remember if that was Tektronix (doubtful), or Lecroy, or Nicolet... or some other manufacturer.
LeCroy definitely used amber.
