The photoluminescent pigment is made of activating alkaline earth aluminate with rare earth elements.
They can glow in darkness for 12 hours continuously after they absorbed various visible lights for 10-20 minutes. Their
luminance brightness and duration are at least 30 times of traditional luminescent materials represented by ZnS:Cu, and can be used repeatedly .

The test results issued by National Institute of Metrology (NIM) demonstrate that the product is nontoxic, radioactive free, and has stable chemical performance.
It can be made into various photoluminescent products, and have been widely used in
screen printing, ink, fire prevention, place-name signs, household electric appliances, clocks and watches, craftworks and gifts,
and so on.
