Green Synthesis of 8-Hydroxyquinoline Barium as Visible-Light-Excited Luminescent Material Using Mechanochemical Activation Method.

ABSTRACT: Using high-energy UV-light to excite 8-hydroxyquinoline barium (BaQ2) is a short slab for this emerging area of organic luminescent materials. However, using visible light to excite BaQ2 has not been reported. To solve this problem, this study proposes the mechanochemical activation method to synthesize luminescent material of visible-light-excited BaQ2. This research applies infrared spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, and fluorescence spectrometry to analyze the structure and luminescence properties. XRD shows that BaQ2 has a high crystallinity, small crystalline size, and high purity. According to the Scherrer equation, the mean particle size is 56 nm. The results of fluorescence spectrome
