Abstract

This activity highlights fundamental aspects of fluorescence phenomena using a homemade fluorometer constructed from items readily available in the home. The activity investigates the fluorescence of highlighter marker ink using a flashlight or white LED as a light source, colored cellophane sheets as filters, and the human eye as a detector. The activity relates to the concepts of excitation and emission, Stokes shift, and the dependence of fluorescence on the intensity of light.
