How does glow in the dark paint work

To reply your question, we have to speak about light. This is not a straightforward thing to do. About 100 years ago, the world’s smartest scientists even argued about what light really is. And they argued for a lot of years.

Light is definitely a bunch of tiny things that scientists call “photons”. These little things can journey unbelievably quickly.

How shortly? Well, imagine this: photons can go across the total world more than seven occasions in just one second.

When these photons reach our eyes, we see them as light. The more photons there are, the brighter the light.

Photons can come in all the colors of the rainbow. In addition they hold energy which can turn into heat. This is why it feels warm when the sun shines.

But, not all light is the same. Blue and violet photons both have more energy than red ones, for example.

Invisible light

Now here’s a bizarre thing: there are some types of light which might be invisible!

For instance, ultraviolet (UV) light, which has even more energy than blue and violet light, is invisible.

Sunlight contains some of this highly effective UV light. Because it has so much energy, it will probably cause lots of damage, like sunburn, for those who get too much of it in your skin.

One other invisible type of light is infrared light. Infrared means “less than red”, so this light has even less energy than red light.

Making paint glow

Many light sources, just like the Sun or an old light bulb in your lavatory, glow because they are really hot. Normal glowing, like that of the Sun and a light bulb, requires objects to be really sizzling for us to see it.

As you already know, you may see glow-in-the-dark paint, paintglow australia but for those who touch it, it’s just as cold because the bedroom wall. So, the glowing of the paint have to be totally different to the glowing of a light bulb.

The paint has a particular kind of glowing called “luminescence” and it will probably only be created from a number of types of material. One such material is what scientists call “luminescent phosphors”, and this is what makes your paint glow. Scientists make luminescent phosphors in the lab by mixing special chemical substances together, after which add them to the paint. The paint is then sold to factories and manufacturers who put it on toys, stickers, and even inside colouring pens.

While some things glow on a regular basis, like the sun, glow-in-the-dark paint must be “told to glow”. Just like your mother and father have to charge their phones every night time to make them work, these supplies should be “charged” before they start glowing.

In truth, the charging of your glow-in-the-dark paint is finished by different types of light. The invisible UV light with lots of energy can charge the particular phosphors in your paint and make it glow in your bedroom at night.

There are totally different types of glow-in-the-darkish paint. One type might be charged during the day and might glow for hours at the hours of darkness at night. The charging that occurs throughout the day, for instance by sunlight, is stored in the paint for a while, just like within the battery of a phone.

This type of paint is called phosphorescent. The other type, called fluorescent paint, only glows while an invisible UV light is turned on to cost it.
