I. Intruduction
The rare earth-activated alkali earth aluminate-silicate
photoluminescent pigment compounded by high-temperature
solid phase reaction, is a novel, long-efficiency and
environmentally friendly material.
II. Product characteristics
1. Photoluminescent pigment is a light-yellow powder,
turns to green color after being excited by light.
2. The smaller the particle size,the lower the luminance
is.
3. Compared with other pigments, photoluminescent pigment
can be easily and widely used in many fields.
4. High initial luminance, long afterglow time (Test
according to DIN67510 Standard, its afterglow time can
be 10,000 minutes)
5. Its light-resistance, aging-resistance and chemical
stability are all good (more than 10 years of life span)
6. It is a new type of environmentally friendly photoluminescent
pigment with the characteristics of non-toxicity, non-radioactivity,
non-flammability and non-explosibility.
III. Application Scope
It can be used in many transparent or translucent media,
such as plastic, paint, glaze, ink, glass, printing
slurry etc. to produce luminous products. With the good
indicating and beautifying effect in darkness, it can
be widely used in emergency signs, passway signs, switches,
enamel nameplate, road signs, toys, handicraft, clock,
meter panels ,textile, firemen's equipment, military
and camp instruments etc.
