用Grasshopper光束线测量了β-B-105、B_4 C、h-BN、B_2O_3和BPO_4以及K_2 O-SiO_2-B_2O_3系统光纤玻璃的B K边X射线吸收近边结构（XANES）谱。B K边的化学位移与B的氧化态、配体的电负性和Br的配位几何有关。
B K-edge x-ray absorption near-edge structure (XANES) spectra of beta-B-105, B4C, h-BN, B2O3 and BPO4, as well as optic fiber glasses in the K2O-SiO2-B2O3 system, are reported using a Grasshopper beamline. The chemical shift of the B K-edge is correlated with the oxidation state of B, electronegativity of ligand and coordination geometry of Br The coordination of B in K2O-SiO2-B2O3 glasses is also investigated.
