On the afternoon of June 9, 2021, Professor Liao Qing from the Department of Chemistry of Capital Normal University was invited to the University of Chinese Academy of Sciences to give a lecture on the theme of "Organic Micro-Nano Laser and Low-Dimensional Photonic Materials". The lecture was held in Room 214 of the first teaching building.

    Photonics is the science of using photons as information and energy carriers, involving application technologies and devices such as light generation, transmission, detection, amplification and display. Organic photonics materials have received extensive attention due to their advantages in optical properties, flexibility, and processing costs.

    In the lecture, Professor Liao Qing clearly introduced the achievements of his team in recent years. The main research direction of the team is "organic micro-nano crystalline materials and devices", and the lecture content is divided into laser in organic micro-crystal micro-cavities In terms of photonic regulation and control, Prof. Qing Liao introduced his team's work on singlet laser materials, triplet-assisted photon lasers and exciton polariton lasers. Finally, we exchanged and discussed with the teachers and students on site from the aspects of the structure, properties and application fields of organic materials, and the current situation of industrial development. The students expressed that they have benefited a lot.
