What is it? Light that is not generated by high temperatures Occurs at low tempteratures Form of cold body radiation

Different types Chemi-luminescence Bioluminescence Crystalloluminescence Electroluminescence Cathodoluminescence Mechanoluminescence Triboluminescence Fractoluminescence Photoluminescence Fluorescence Radioluminescence Thermoluminescnece

What do you think this would fall under?

Triboluminescence This is normally caused by rubbing Go Back

Thermoluminescence This type is released in the form of light when a mineral is heated. Go Back

Bioluminescence This is the production and emission of light by a living organism as the result of a chemical reaction during which chemical energy is converted to light energy Next

Diamonds are Forever… But what are they? Really? Click me to find out. Triboluminescence Photoluminescence Radioluminescence

Triboluminescene It usually glows when it is being rubbed or cut It usually glows blue or red

Maybe or Maybe not… But first…

Nah!!! I not that mean
