    Name: Liujianjun BirthDate: 1992-06-13 Time of Joining OUC: 202305
    Research Direction:luminescence of solids
    PersonalProfile: I have focused on the systematic research of novel organic- and nano-semiconductor materials and their optoelectronic applications over a long period. Using key spectroscopic techniques and mathematical tools, I have pioneered new perspectives for the study of the physical and chemical properties of these materials and their optoelectronic device applications.Until now, I have published 23 high-level academic papers in Nature Photonics, Chemical Science, and other internationally renowned academic journals. The papers have been cited over 400 times with an H-index of 13 in Google Scholar. Two Chinese invention patents have been granted, and our reported materials have been listed and sold on international semiconductor companies’ websites (LUMTEC and J&K Scientific) for commercialization. I have been an independent reviewer of Chinese Chemistry letters and established broad cooperation with international experts in this field.
    WorkExperience: 2023.05-- now: Ocean University of China Associate Professor 2019.10-2023.02: RIKEN, JAPAN. Postdoctoral Researcher
