[Press Release] Environmentally Friendly Photonic Luminescent Microbeads with Tunable Emission from Visible to Near-Infrared: Developed Using Plant-Derived Materials as Main Ingredients

A NIMS research team has successfully developed environmentally friendly microbead-type luminescent materials using citric acid and other plant-derived ingredients. These microbeads emit different colors of light depending on the illumination and bead size, making them suitable for various applications. The use of plant-based materials enables synthesis at low cost and with reduced energy consumption.

This research was conducted by the MANA Nanophotonics Group (led by Dr. Tadaaki Nagao), Solid-State NMR Group, Center for Basic Research on Materials, and High Magnetic Field Characterization Unit, Research Network and Facility Services Division at NIMS.

The results were published in the online edition of Advanced Science on June 13, 2024.
