Green Synthesis of 8‐Hydroxyquinoline Barium as Visible‐Light‐Excited Luminescent Material Using Mechanochemical Activation Method (Global Challenges 12/2019)

In article number https://doi.org/10.1002/gch2.201900052, Xueming Zhong and co‐workers propose a mechanochemical activation method to synthesize 8‐hydroxyquinoline barium, which is of interest as a luminescent material for energy applications. The synthesized material can photoluminesce under 408 nm visible light and has a higher crystallinity and smaller particle size than that synthesized by the traditional liquid‐phase method.
