Introduction
The rare earth-activated alkali earth aluminate-Strontium(Sr) photoluminescent pigment, with the chemical formula of MO·aAl2O3·bSiO2·cL: Eu2+Dy3+, compounded by
high temperature solid phase reaction, is a novel, long-efficiency and environmentally friendly material
Luminescent Mechanism:
at a certain wavelength of light exposure, material was inspired after the ground-state electron in the molecule absorbs energy, a transition is made to high energy track. However, due to the high
energy orbit is not stable, electronic spontaneous transitions back to the original track while emitting energy in the
form of light.
when there is light again, it stores energy again. So the photoluminescence process is circulatory.
Characteristics:
1. Starting High Brightness: in sunlight or under light irradiation 10 minutes starting brightness more than
10000mcd/m2
2. Long afterglow time: optical absorption in the day, dark glow over 10 hours, its luminous intensity and the
maintenance time is 30 times more than traditional luminescent material.
3. Safety and friendly to Environment: non-toxic, harmless, non-inflammable ,non-explosive and irradiation free;
4. Weathering good: material stability and weathering resistance ,excellent in outdoor use without limitation, can
be unlimited time cycle to shine.
Application fields:Suitable for various kinds of transparent medium, such as paint, screen printing, plastic, glass, coating, powder
coating, ink, enamel, ceramic and fiber.Indication position:Can be applied in switch of home appliance, control board, plug, lock, electric torch, stairway, fire protection facility,
fire alarm, lifesaving tools etc.Safety fields:Show safety indication effect in fields as below: Signs, warning items writing, emergency passenger way, subway
station, underground passage, blindage project, hospital, dancing hall, video room, refuge shelter, helmet, bicycle
etc.Building: Can be applied in building wall, tiles, inside surface of elevator, bridge, roads, sea ports etc. Both
decoration and application value has been achieved.Others:Arts and crafts, amber, sand crystal, glass, painting works; toys: Plastic toys and piece together pictures; clothing:
Shoes, caps, working uniform, helmet, transfer pictures, printing graph clothing; calendar, fishing tools.
