Fluorescence under UV Light – 7B13.50

- Shine a black light on various minerals causing them to fluorescence.

Location: Jacobs B122 - Shelves 299 & 166

Quantum Dots – 7B13.52

- Quantum dots are small spheres (2-50nm) composed from a semiconductor.
- The size of the dots determines the wavelength of light that is emitted.
- Various LEDs are used to show that a minimum energy is required to achieve fluorescence.

Phosphorescence – 7B13.53

- Shine a blue LED on a piece of “glow-in-the –dark” phosphorescent material.
- It absorbs the energy and “stores” it and stores it for a long time as the subatomic reactions required to re-emit the light.
