Professor Sooseok Choi’s research team has developed a novel technology for freely tuning the color of omnidirectional wavelength-stretchable nanostructure color. The research paper was published in Light: Science & Applications (LSA).

Professor Sooseok Choi’s research team, consisting of Seungmin Nam (Ph.D. student, first author), Wontae Jeong, and Junhyeok Shin (under the supervision of Professor Sooseok Choi), has developed the first-ever nanostructure color wavelength tuning optical device that overcomes the limitations of previous research in color wavelength control. This device allows for precise and free adjustment of color wavelengths in both short and long wavelength directions.
