The Performance of Color-Television Picture-Tube Phosphor Screens
Austin E. Hardy
[Radio Corporation of America Electronic Components and Devices, Lancaster, PA]
IEEE Transactions on Broadcast and Television Receivers
Year: 1965 | Volume: 11, Issue: 2 | Journal Article | Publisher: IEEE

Hardy's list of red phosphors stops with yttrium vanadate rare earth doped with europium, so apparently the yttrium oxysulfide:europium was not yet used by RCA.
