On the topic of Europium-doped color CRT Red phosphor, snapshot of a Sylvania advert found browsing through old issues of Electronics magazine, Dec 1964.
The entire library is on World Radio History.com

From memory, the "definitive" Red phosphor was Yttrium Vanadate, Europium-doped and was used until the end of color CRTs.

I believe the vanadate was the earlier rare earth red, and within a short time the industry settled on yttrium oxysulfide, europium doped.
