Abstract
PURPOSE: A fluorescent substance emitting blue color, prepared by doubly activating Zns with specific amounts of Ag and Cu, and adding Cl as a coactivating in an amount corresponding to the total chemical equivalent of Ag and Cu thereto, and having improved brightness and chromaticity characteristics and a long afterglow effect.
CONSTITUTION: Zns is doubly activated with 0.01W0.04wt%, based on the fluorescent substance, Ag and 0.00001W0.0001wt%, based on the fluorescent substance, Cu, and Cl in an amount corresponding to the total chemical equivalent of Ag and Cu as a coactivating agent is added thereto to give the aimed hexagonal fluorescent substance emitting blue color.
EFFECT: Slight flickers.
USE: Suitable for terminals of electronic computers and display color cathode- ray tubes for controlling and monitoring plant systems.
