Abstract

1,229,058. Luminescent materials. SYLVANIA ELECTRIC PRODUCTS Inc. 26 April, 1968 [15 May, 1967], No. 19897/68. Heading C4S. A Eu activated YVO 4 phosphor is coactivated with 7À2 to 11À0 x 10<SP>-3</SP> gm. atoms Tb per mole of YVO 4 ; Bi and Pr may be present. The phosphor is prepared by heating a mixture of Y, Eu and Tb oxalates, and NH 4 VO 3 then rinsing the product in NaOH. The phosphor is used in colour T.V. tubes.
