High Luminous Safety Noctilucent Powder Pigment
What is photoluminescence?Lightlead photoluminescent materials (commonly called “glow-in-the-dark”) has the ability to absorb light (sunlight, fluorescent, incandescent,etc) and then to emit light.
When ambient darkness occurs, it becomes highly visible, lasting at least 8 hours. Our best products
could last more than 20 hours. Upon removal of the light source, the stored light is gradually released, the strongest glow is produced during
the first 30 minutes of darkness, the most critical period following a power failure or other emergency. Then it fades
over a period of time, when there is light again, it stores energy again. So the photoluminescence process is
circulatory. The bases of most photoluminescent products are photoluminescent pigments that can be incorporated into coat,
paint, ink, fabric, ceramic glaze or porcelain enamel, glass, flexible and rigid molded plastics. Typical products
include self adhesive flexible vinyl tapes, rigid PVC marker strips, and silkscreened signage.
Photoluminescent fabric, enamel-coated sheet metal and ceramic tiles are also available.
What is Strontium Aluminate pigment?Recent research efforts have produced several new inorganic compounds whose photometric characteristics
greatly exceed those of zinc sulphide compounds. These materials include oxides of strontium aluminate
(identified as SrAl) and other proprietary inorganic compounds. These compounds offer much brighter and longer-lasting photoluminescence, and they can formulate (unlike zinc sulphide compounds) to produce a range of colors.
Is it environmental products?Lightlead photoluminescent materials are non-toxic, non-radioactive and contain no phosphorus or lead, or any other hazardous element or chemical.
The term phosphorence is sometimes used to describe luminescence, but Lightlead photoluminescent materials
contain no phosphorus. Lightlead photoluminescent materials differ from reflective materials, which amplify and increase relative brightness
when light is applied. Fluorescent materials are quite different from photoluminescent materials. Fluorescent
materials (such as the 3M fluorescent work zone film or a "hot pink" tag) actually serve to borrow nearby light energy
in nearby wavelengths and concentrate the amount of light returning to the viewer in a certain (for example, day-glo orange) wavelength. Fluorescent films are especially useful in dawn and dusk viewing times, when they appear
particularly bright.Lightlead photoluminescent materials require prior exposure to a light source in order to glow in
the dark.
