And so before you get creative with your glow in the dark paint and decorations, have a think about how much ambient light will be around the item, do bare in mind that even moonlight or street lighting shining in through a window is considered ambient light and will prevent your eyes from adjusting totally to darkness. This is also why night vision goggles typically colour things green.
Glow in the dark products are best viewed in total darkness as the eyes are allowed to adapt, perceiving a much brighter glow.Įver wondered why glow in the dark stuff is green? It's because the human eye is most sensitive to green light and so green glow in the dark products appear brighter. In fact the glow will appear to be brightening the more adapted your eyes become!Īmbient light affects the perceived glow of photoluminescent materials as the light draws your eyes and detracts them from the darkness. The more adapted to the dark your eyes are, the brighter the glow that you will see. How adapted your eyes are to the dark will affect the brightness of the glow that your eyes perceive.
21-23 mins of fluorescent light (strip lighting or energy saving bulbs).Ultra violet light works best and charges in the fastest time.Īpproximate charge times for glow in the dark products are as follows: Remember, the phosphors need to absorb light to re-emit light and some light is better absorbed than others.

Glow Padel means that a padel match or tournament is played in the dark, on a padel court lit by blacklights (also called UV lamps). Glow in the dark luminance fades after time. Strontium aluminate has a much longer persistence (glow time) than zinc sulphide and so higher quality glow products will use this phosphor over the latter. Most glow in the dark pigments and materials use the phosphors zinc sulphide or the newer strontium aluminate which produces a brighter glow over a longer period of time. Glow in the dark or photoluminescent materials carry inorganic phosphors that absorb light in the visible and ultra violet wavelengths and then re-emit visible light, or a "glow". Glow in the dark is a much loved phenomenon that engages kids and adults alike and adds that little extra magic to toys and room decorations (think glow in the dark stars), but just what is glow in the dark, and how does it work?
