Solids & Light

Energy quantization is applied to luminescent materials such as light sticks, glow-in-the-dark toys and infrared detectors. Students see how they can build energy level models to explain a variety of different light emitting processes. Prerequisite: A knowledge of conservation of energy & potential energy diagrams.
