How do I make my Glow in the Dark products glow?

All glow in the dark items need to be charged, by exposing them to a bright light.

In the case of glow in the dark stars (or similar items such as teddies, dinosaurs, flying pigs, etc) that you might stick on your ceiling, or glow paint that you have used on the ceiling, the light that you normally use in the room (e.g. a 60W ceiling light) should be sufficient. If your room is unusually dark (for example if you have a 40W bulb with a thick shade) you may find that you need to brighten things up a bit to charge your stars.

For other items, such as glow in the dark gadgets or toys, you should hold them up to a light source (e.g. a lamp). They should be close to the light source for effective charging, but do take care because light sources get hot, so don't get too close, and please don't look directly at the light source as you may damage your eyes. To charge body jewellery, you should remove it before exposure to the light source to reduce the risk of injury.

A few seconds of charge should be long enough to produce an effect, but you may prefer to charge for a few minutes as this will make your items glow better.

What do they look like when they are glowing?

Glow in the dark products produce a glow which will enable you to see them clearly, but they do not cast much light onto other things - a ceiling full of glow stars should be clearly visible when properly charged, and will produce a lovely display, but please don't think that it will give out enough light for you to read by! Glow products are more visible in complete darkness.

Glow products usually glow green or yellow, regardless of what colour they are in natural light. All glow in the dark items also glow during exposure to UV light (also known as club light or black light), and interestingly, may glow a completely different colour in UV light to that seen in natural light or when glowing in the dark.

How do they work?

Glow in the dark products contain ‘phosphors’, which radiate light after being charged, because of ‘phosphorescence’. Phosphor molecules absorb energy during charging, and enter an ‘excited state’; when charging ends, the phosphors release the stored energy by glowing, or ‘phosphorescing’.

There are many different phosphors, and ones used in products such as glow stars are selected for their ‘persistence’, which is the length of time that they will glow for once charged, and for their ability to be charged by daylight or normal artificial light (some phosphors require other energy sources to charge them).

Zinc Sulfide and Strontium Aluminate are the most common phosphors for novelty glow products; for plastic products the phosphor is usually mixed in with the plastic before moulding.

Contrary to some urban myths, the phosphors used in novelty glow in the dark products are completely safe! You can find phosphors in almost every home and office – they are used in TV screens and fluorescent lights.

The above information is a guide only. Always take care when charging your glow products! Glow stars etc can be used in children's rooms as long as they are firmly affixed out of reach, but unless otherwise stated glow products are not suitable for children under the age of 3 years to handle.
