On September 10, 2019, at 15:30 pm, Professor Koen Clays and Professor Mark G. Humphrey gave a lecture on the theme of "Colloidal photonic crystals" at the A310 School of Chemistry and Materials Engineering. Zhang Jinfang, a professor of the School of Chemistry and Materials Engineering, presided over the lecture. In the lecture, Professor Koen Clays and Professor Mark G. Humphrey discussed the theory of colloidal photonic crystals, the discoloration of colloidal crystal materials with air humidity and the scientific problem of changing the passband of colloidal photonic crystals through defect design. In the lecture, Professor Koen Clays show self-made colloidal tablets to the teachers and students of the School of Chemistry and Materials Engineering, and the phenomenon of discoloration was demonstrated. Prof. Koen Clays and Professor Mark G. Humphrey answered the questions raised by the teachers and students of the School of Chemical Engineering.
