How does glow in the dark paint work

To answer your question, we need to discuss light. This will not be a straightforward thing to do. About one hundred 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 rapidly? Well, imagine this: photons can go around the entire world more than seven times 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 are available all the colors of the rainbow. Additionally they hold energy which can turn into heat. This is why it feels warm when the sun shines.

However, 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 weird thing: there are some types of light that are invisible!

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

Sunlight incorporates some of this powerful UV light. Because it has so much energy, it will probably cause a number of damage, like sunburn, if you get an excessive amount of 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 rest room, glow because they are really hot. Regular 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 possibly can see glow-in-the-darkish paint, however if you contact it, it is just as cold because the bedroom wall. So, the glowing of the paint must be different to the glowing of a light bulb.

The paint has a special form of glowing called “luminescence” and it can solely be created from just a few 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 chemicals together, and then add them to the paint. The paint is then sold to factories and producers who put it on toys, paintglow australia stickers, and even inside colouring pens.

While some things glow all the time, just like the sun, glow-in-the-dark paint have to be “told to glow”. Just like your dad and mom must cost their phones every night time to make them work, these supplies need to be “charged” before they start glowing.

In actual fact, the charging of your glow-in-the-dark paint is completed 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 completely different types of glow-in-the-dark paint. One type may be charged through the day and might glow for hours at the hours of darkness at night. The charging that occurs through the day, for instance by sunlight, is stored in the paint for some time, just like in 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 charge it.
