Glow in the Dark Paint Doesn’t Need Sunlight
Unlike conventional glow in the dark material, this new stuff doesn’t need any exposure to sunlight or artificial light to give off useable light for over 12 years. It uses microspheres which house some radioactive gas to produce the light. Luckily, the sphere construction prevents rupture, so there’s no worries about getting accidental exposure to unwanted radiation.
A while back, electroluminescent materials were the new ‘big thing’, and while they provided a cool lighting effect for a low price, they still need power to run. If the claims hold true for this material, we could have a very useful and widespread tool for emergency lighting and safety markings in a few years.
