Description:

The basic formula of rare earth aluminate long persistence phosphor is SrAlO4: Eu, Dy. By modifying its composition with different additives, the phosphor can emit a color of green, yellow, blue, white or other colors. After activating by either visible light or ultraviolet, its emitting duration can reach up to 12 hours and its intensity is much higher than zinc sulphide (ZnS). These features make the rare earth long persistence phosphor a much better candidate over other phosphors such as ZnS in many applications. Currently this phosphor is widely used as a pigment added into paints, rubbers and plastics for applications such as billboards, traffic signs, decorations and toys.

Applications:

I. Applications of long persistence phosphor in paint and printing ink as a pigment.
II. Applications of long persistence phosphor in screen printing, printing, printing and dyeing starch.
III. Applications of the Long persistence phosphor in luminous plastic granule for plastic molding
