摘要:

草酸二芳基酯-过氧化氢化学发光体系是一种原理简单、效果明显、趣味性强的化学发光体系。通过体系中的染料将反应的化学能转变为光能,广泛应用于发光玩具、紧急照明、搜寻救援等领域。根据所使用染料的不同,化学发光可以发出不同颜色的可见光以及肉眼不可见的红外光。本科普实验通过多种化学发光染料,介绍了化学发光的原理和红、绿、蓝、红外发光的波长范围,以及展示了利用红光、绿光、蓝光实现多种颜色发光的原理。本文设计了不同染料的混合发光、火山喷发模拟、自制化学发光荧光笔、粉笔彩色发光、自制荧光棒等多组化学发光科普实验和互动环节,寓教于乐,生动有趣。

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
