Examples are: ZnS, CdS, Y2O3, Y2SiO5, ZnSiO4 etc.
Fluorescent light bulbs use phosphors to convert ultraviolet light into visible light.
The element primarily used in making phosphors for televisions is zinc, specifically in the form of zinc sulfide (ZnS). Other elements like europium and terbium are also used to create red and green phosphors, respectively. These phosphors emit light when excited by electrons, allowing for the display of colors on screens.

Glow paint typically contains phosphors that emit light once they have been charged by ambient light sources. These phosphors trap light energy and slowly release it over time, creating a luminous effect that glows in the dark. The paint may also contain binders and pigments that help hold the phosphors together and provide color.
For example the socalled phosphors. see the link below
Fluorescent light bulbs use phosphors to convert ultraviolet light into visible light.
Some items that contain phosphors include fluorescent light bulbs, cathode ray tube (CRT) television screens, and computer monitors. These phosphors emit visible light when excited by ultraviolet radiation or electrons.

Although I would not recommend it, yes you can as most are non-toxic.If however you meant elemental Phosphorus instead of phosphors, NO, some form of Phosphorus are deadly poisons and white Phosphorus spontaneously ignites on contact with air!!!If you don't know the difference between phosphors and Phosphorus, that is the subject of a different question.
Phosphors for fluorescent lights are one.
they have a chemical in them
Glow paint typically contains phosphors that emit light once they have been charged by ambient light sources. These phosphors trap light energy and slowly release it over time, creating a luminous effect that glows in the dark. The paint may also contain binders and pigments that help hold the phosphors together and provide color.
Highlighters glow because of the phosphors that the black light contain and because of its chemicals in it.
For example the socalled phosphors. see the link below
Glow in the dark items contain phosphors, which are materials that store light energy when exposed to light. When the lights are turned off, the phosphors slowly release this stored energy as visible light, creating the glowing effect.
