chemistry of glow in the dark
What is the principle of glow-in-the-dark?
Photoluminescent products contain phosphors, that when energised by light, glow in the dark.
The phenomenon of photoluminescence is created by the absorption of visible, UV or Infra-red radiation and is a non-radioactive process.
The pigments absorb and store photons or 'particles' of light from the light source.Phosphorus.
Phosphorus, like plutonium, glows because it is reacting with oxygen in the air.
Phosphors and phosphorus glow an eerie green.
Although the element glows, phosphorus is not radioactive.
What is the chemical in glow-in-the-dark?
Glow-in-the-dark toys have phosphorescence.
That means they contain special substances called phosphors.
Phosphors give off visible light after being energized.
What is the composition of glow in dark?
The glow in dark composition is comprised of 25-60% by weight of photo-luminophore made from the chemical family alkaline earth metal aluminate oxides (Sr2A12O4) and 0-20% by weight of a powdered solid solution of dyestuffs in a thermoset suiphonamidemelamineparaformaldehyde resin.
