Abstract:

The diaryl oxalate-hydrogen peroxide system is a chemiluminescence system with simple principles, obvious effects, and great fun. The chemical energy of the reaction is converted into light energy through the dye in the system. It is extensively used in light-emitting toys, emergency lighting, search and rescue, and other fields. Depending on the dyes used, chemiluminescence can emit colorful visible light and invisible infrared light. The scientific experiment discussed in this paper used several chemiluminescence dyes to introduce the principle of chemiluminescence, the range of red, green, blue, and infrared emission wavelengths, and the principle of using red, green, and blue light to achieve multiple colors. In this paper, we designed several scientific chemiluminescence experiments such as the mixed luminescence of different dyes, volcanic eruption simulation, homemade chemiluminescence highlighters, the colorful chemiluminescence of chalk, homemade light sticks, etc. These experiments are entertaining, lively, and interesting.

Key words: Chemiluminescence, Diaryl oxalate, Hydrogen peroxide, Visible light luminescence, Near-infrared luminescence
