Abstract
Sodium tetraborate decahydrate was used as boron source, polyethylene glycol was used as the polymerization agent, and nano-Mn3B7O13Cl was prepared by citric acid method with various pH values and mass ratios of citric acid to water. The microstructure, surface morphology, and luminescent properties of the samples were analyzed by XRD, SEM, and fluorescence spectrometer. The results show that the rhombic crystal structure of nano-Mn3B7O13Cl was prepared successfully, and the particle size ranges from 40.3 to 65.7 nm. The smaller the water content and pH, the smaller the particle size and the better the dispersion. At the excitation wavelength of 254 nm, there is a strong emission peak at 429 nm, and the emission intensity is maximum. Under the monitoring wavelength of 564 nm, there is a peak at 460 nm corresponding to a transition of 4T1–6A1, which is the cause of the luminescence of nano-Mn3B7O13Cl, the d–d conversion of Mn2+.
