Photoluminescent or
glow in the dark products
Over the past
two decades, we have all see photoluminescent or glow in the
dark products. We have seen novely items such as toys at
fair which glow and attract attention, non-powered safety signs
and arrows which direct individuals out of an office or hotel,
photoluminescent ink on clothing, cars, plates, posters and
walls. The use of photoluminescent paints on art--canvas
and glass are also gaining popularity. We have also
started to see photoluminescent thread for embroidery.
Further, pholuminescent pigments and markers are showing up in
security or tamper evidence.
Photoluminescence is a process where a material aborbs
photon energy (light) at one wavelength; stores it by exciting
an electron to a higher energy state; photoluminescence (light
emission) is observed with the excited electron returns to the
lower energy state. The typical process of excitation and
light emission takes 10s of nanoseconds. By arrangement
of molecules and additives, one can extend the photoluminescent
periods to more useful 10 minute to 10
hours.
We will be
seeing a lot more of photoluminescent products in the safety
area over the next few years. Several standards and lows
have been put forward which mandate use of photoluminescent
signage for egress in buildings, boats, subways, rail cars,
etc. Additionally, the standards call for a minimum
afterglow time period resulting in challenges for
manufacturers.
At
Photoluminescent.com, we plan to be a key lead generation site
for everything photoluminescent. This includes
photoluminescent pigments, photoluminescent masterbatches,
photoluminescent inks, photoluminescent paints,
photoluminescent thread, photoluminescent signage,
photoluminescent film, photoluminescent tapes and others.
