摘要采用核磁共振和电子顺磁共振(NMR和EPR)、x射线结构和荧光分析等方法研究了Mg和Fe掺杂的铌酸锂晶体。结果表明,低对称性配合物FeNb-MgLi在镁浓度大于4.5 mol.%时生成。
Abstract Congruent lithium niobate crystals doped with Mg and Fe are investigated by means of nuclear magnetic and electron paramagnetic resonances (NMR and EPR), X-ray structure and fluorescence analyses. It is shown that the low-symmetry complexes FeNb-MgLi are created at magnesium concentration above 4.5 mol.%.
