Using fluorescence spectrometers, the weak-fluorescence substance and the optical filtering properties of Coca-Cola were found out to explain the red shift phenomenon when excited at 532 nm. The quantitative relationship between excitation depth and spectrum was studied using a set of apparatus and a grating spectrometer. This experiment applied many physics knowledge, including fluorescence spectrum, filtering properties etc. A part of the experiment devices needed to be made by students themselves, which could develop their abilities to solve problems in research.
