To answer this, we must understand how black lights work.
Ping Pong Balls are a popular toy in many bedrooms across the United States.
Ping Pong Balls Glow in Blacklight use bulbs filled with mercury vapors which when energized emit ultraviolet light which gives objects an appearance of fluorescent colors. These lights have little to no visible light output so they do not interfere very much with human vision. The most common color seen under these lights is purple because of the long wavelength of light being emitted from the bulb.
If you try these tests around the house with different sources and happen upon one that works well enough, then, by all means, purchase it; but make sure you read the package carefully and look for advertisements claiming “full strength” blacklight power (these packages will also usually contain tubes and other items specifically intended to make your own fluorescent-friendly art). Otherwise, we recommend using a tube blacklight instead.
An important thing to note about fluorescent materials is that they are only able to absorb certain wavelengths of light and reflect back other ones. This means that black lights will not cause all substances to glow. Fluorescent materials can be tuned to emit specific colors by altering their chemical make-up. They are also limited as to how much light they can absorb and still fluoresce (if they reach this maximum capacity, the object under the blacklight will cease to fluoresce and only glows white).

What are ping pong balls made of?
How do you know if a ping pong ball is under the blacklight?
The water-based protective coating is usually colored to match the color of the ball
The inner and outer ink rings are electrically isolated from each other when used to print electrical tracks (unless there’s a big enough electrical potential gradient in which case electrons migrate through solvents like glycerol or ethylene glycol, but not water). The polymer material in between the two conductive carbon ink layers stops this effect here.

Waterproofing means it won’t oxidize (rust). The manufacturer may add extra coatings and varnishes for gloss, color, UV resistance, etc., but if it looks like a ping pong ball under regular light then it’s probably fine under blacklight too.
When you introduce a fluorescent material into a lit environment, it absorbs light and then emits that wavelength at which it was tuned, and the additional energy is absorbed from the light source. By turning a fluorescent material for one color you put it in an environment where two colors of light are present, both of which it is capable of absorbing so only one color might be observed depending on if its absorption of the secondary color is greater than its fluorescence or vice versa.
Two things can determine if a fluorescent material absorbs more light than it emits:
The two colors in most blacklights are 400nm and 315nm with one shorter wavelength and one longer wavelength, which we will use to illustrate how they affect whether or not a certain fluorescent material will glow under them.
If you tuned a fluorescent material to 400nm exclusively, then that material would emit this particular color when exposed to any source of light at 400nm, however, if it is also capable of absorbing 315nm light then that energy is superfluous to its purpose.
Why do they Ping Pong ball Glow in Backlight?
The carbon ink is conductive (helps to carry electricity), but the resistance across the thickness of the ball is still pretty high because it’s a thin film. This means that you need about 1-3 volts for this paint to glow, depending on how big/small your surface area is. If you use too little voltage then no current flows and nothing will glow.
If you run current through it with more than 3V then electrons may start popping out of the semiconductor material in the polymer matrix, creating point defects which are also called “electron traps”. These electron traps absorb photons from incoming light so if your ping pong balls are glowing dimly without any UV light being used it could be because they are absorbing FRESNEL. It might have to do with the angle of the photons in relation to the angle of reflection.
The electrons in each semiconductor are paired up, they spin in opposite directions when excited by an electron, but only if it is not already paired up.
This can be explained using band theory where you have valence and conduction bands separated by the band gap energy. These are filled with electrons at absolute zero temperature. When you heat up a conductive material most of these electrons will move about freely between these bands, which is called thermal excitation or simply heat.
Do all colors react to blacklight or just some colors:
The electrons in each semiconductor are paired up, they spin in opposite directions when excited by an electron, but only if it is not already paired up.
This can be explained using band theory where you have valence and conduction bands separated by the band gap energy. These are filled with electrons at absolute zero temperature. When you heat up a conductive material most of these electrons will move about freely between these bands, which is called thermal excitation or simply heat.
When a light is shined on certain materials this causes its molecules to vibrate faster and emit photons with a wavelength that corresponds to the color of the light being shone upon it. For example. This can be seen in metals that are conductive. When you heat up the material, thermal excitation will cause electrons to move freely between bands. If there is a large difference in free electron density (and thus electrical potential) it will result in electric current traveling through the metal which we call electricity.
Materials like glass or plastic will not conduct electricity when exposed to heat because their band gaps are too large for an electron to easily jump the gap.
Now let’s talk about semiconductors. In physics, a semiconductor is defined as any material that has the properties of both a conductor and an insulator. This means that, like an insulator, its atoms have electrons in their outer shells that are far from the nucleus and therefore do not easily interact with other atoms (it takes a lot of energy to excite these electrons).
However, it also partially acts as a conductor because there are some free electrons already in its outer shell – they don’t stay there forever but can move around to different energy levels within the atom if enough energy is added which we call thermal energy.
