Abstract

This Activity explores some of the fundamental properties of light that is spontaneously emitted from common everyday substances such as glow-in-the-dark stickers, wintergreen-flavored hard candies, and a chlorophyll solution made from spinach leaves. Students are led to explore the different properties of fluorescence, phosphorescence, and triboluminescence. Teachers are provided with a background in the molecular properties that give rise to these different luminescent phenomena, which derive from the fundamental interaction of light and matter.
