On October 9, 2023, the Photonic Nose and Molecular Materials Group held an academic meeting and invited Prof. Zhang Zhenglong of Shaanxi Normal University’s School of Physics and Information Technology to give a presentation at the Lecture Hall of the Institute of New Concept Sensors and Molecular Materials. All faculty members and graduate students of the group attended the meeting, which was moderated by Prof. Liu Jing.

Firstly, Zhang Zhenglong introduced the research progress of surface-enhanced fluorescence, and raised three scientific questions, namely, how to achieve ultrafast and ultra-intense luminescence of rare earths in nanosecond scale, how to achieve fine tuning of rare earth luminescence frequency domain and spatial domain light field distribution, and how to achieve the optimization of the structure of rare earth nanosystems.Then he gave a detailed explanation on two strategies to solve these problems, namely, the near-field modulation of luminescence of rare-earth nanosystems from near-field modulation, and the near-field modulation of physical structure and luminescence properties of rare-earth nanosystems from equi-excitations, pointing out that the method has the advantageous features of in-situ, fast, controllable, and low-temperature applicability, and a certain degree of universal applicability.

Fang Yu affirmed Zhang Zhenglong’s work results and research attitude in his concluding remarks, and called upon the group teachers and students to have a positive attitude towards their work.

Zhang Zhenglong answered the questions from the teachers and students present, and took a photo with the participating teachers.
