The chemistry is similar, although still evolving ... but even when you use the same phosphor the optimal coating won't be the same when using 10 KeV electrons or UV from a plasma discharge, nor it's longevity.For the record, CRTs and Plasmas use the same phosphors.
Stuff like charge buildup is almost completely irrelevant to CRTs (other than rocketing dust into your eyes) yet a major source of IR in plasmas ...This is why plasmas have similar IR and burn-in issues to CRTs and why their persistence and color accuracy is so much better than LCD.
PS. now SED displays, those would have behaved pretty much like CRTs assuming the electron guns didn't suffer from wear.
