Maxiumum Brightness. This is a slightly large particle size glow powder. Of all our UltraGlow® glow-in-the-dark powders, this is the brightest. The larger particle size of the material allows for more efficient energy transfer between the molecules which in turn produces a brighter glow. Unlike our other glow powders that have a very fine particle size of 30 microns, our Coarse Green UltraGlow® powder has a larger particle size of 95-120 microns, making it less 'powdery' and more granular. The granulation is not as coarse as table salt, but it is somewhere between table salt and talcum powder. Due to the larger particle size the powder is somewhat heavier and will settle out faster if mixed with a thin, clear paint. If you are mixing it with a thick base like wax or gel, this won't be a problem, but it is something to keep in mind. Because of the slightly larger particle size, it pours much easier than our fine powdered glow colors which may be important if you plan on using it in an automated manufacturing process. Our Europium UltraGlow® phosphorescent (glow-in-the-dark) powder is the brightest, longest lasting, non-toxic & non-radioactive, glow-in-the-dark material known. Based on the Rare-Earth element Europium, UltraGlow® powders are a new generation phosphorescent material with an astonishing glow time as long as 30 hours!
UltraGlow® is a new generation Phosphorescent material at the cutting edge of chemical phosphorescent technology.
UltraGlow® powder can be mixed with anything from clear paint, to wax,
plastic, clear nail polish, gel, plastics, glaze, etc.
Several large manufacturers purchase this material
from us in large quantities to produce a variety of unique glow items from
paint to candles to plastic glow toys. For use in paint, best results are obtained by mixing as much
glow powder as possible in a clear, non-water based paint. This glow paint should them be painted
over white which acts as a reflector enhancing the visible glow. Painting glow
paint over a black or dark surface will reduce the visible glow
dramatically. Europium UltraGlow® powder can be recharged
indefinitely just by holding it under bright light.
powder is highly heat resistant. It can be mixed with glaze and fired in a kiln
to make pottery and other ceramic items. Its temperature limit is about
Charging up UltraGlow® Powder
ordinary indoor lighting as well as UV
(blacklight) can be used to "charge up" Europium UltraGlow® powder. The more UV wavelengths
the light contains, the faster it will charge. Sunlight (3,000 - 50,000 lux light level) will charge up the powder the fastest, requiring only 5 minutes of exposure.
A 'workshop type' Fluorescent lamp (500 lux light level) is rich in UV light - holding the powder close to a bright fluorescent lamp will charge it up in about 10 minutes. An ordinary 60 watt incandescent (tungsten filament) lamp (30 to 50 lux light level) will take 30 minutes to charge up the powder due to the lack of UV wavelength in incandescent bulbs. UV (blacklights) will charge up the material extremely fast.
The following is information for those that are interested in some of the more technical aspects of UltraGlow:
The Excitation Energy is 200nm to 450nm. Peak Emission Wavelength is 520nm. Europium UltraGlow® powder has excellent Light Fastness compared to other glow materials. Other glow powders will degrade if constantly exposed to bright light. In 15 to 100 hours of exposure, the glow properties of ordinary glow powders become permanently reduced to a fraction of what they originally were. Not so with Europium UltraGlow® powder! Even after 1,000 hours under direct exposure to intense mercury vapor light, Europium UltraGlow® powder retains 96% of its glow output.
In short, Europium UltraGlow® powder is a revolutionary glow-in-the-dark material. Its only limit is the user's imagination.

Glow Intensity & Duration
unfamiliar with Phosphorescent material have unrealistic expectation of how it
performs. Europium UltraGlow® powders are a new generation of glow material
much different than the old Zinc Sulfide based glow products of the past. In
daylight, all the Europium UltraGlow® powders appear off-white in color. When fully charged, all glow powders will produce a bright afterglow for a short time, level off to a
moderate level of brightness, slowly dimming over the remainder of the
The Green and Aqua glow powders will remain clearly visible for as long as 30 hours. The length of time a glow powder is said to 'glow' is defined as the time it takes for the afterglow brightness to diminish to 0.32 mcd (0.32 mcd is 100 times the Human visible perception limit). Even at this level, the glow is clearly visible in darkness.
The Green and Aqua are comparable and by far the brightest and longest
afterglow. Obviously, the level of glow at 14 hours is not nearly as bright as it is at 10
minutes after light exposure, but you can plainly see it in the dark
The Blue glow powder has a lower glow brightness and shorter afterglow duration compared to the Green and Aqua. This is partly due the response of the Human eye. Our eyes are much more sensitive to the color green as compared to blue. Green will always appear brighter to the eye.
The Violet is the least bright of all the glow colors.
All colors can be used as Fluorescent glow powders, that is they will all glow at full
intensity under UV (blacklight) as long as the light is shining on them.
