摘要 合成了 Li3InBr6 和 NaInBr4,并通过 DTA、81Br NQR、6Li、7Li、23Na 和 115In NMR 以及交流电导率进行了表征。这些测量揭示了两种化合物中存在相变和阳离子扩散。根据 81Br NQR 的自旋晶格弛豫时间以及 7Li 和 23Na NMR 谱的峰宽,推断出传导是由于阳离子扩散所致。 Li3InBr6 的 Li+ 扩散活性能为 24 kJ/mol。
Abstract Li3InBr6 and NaInBr4 have been synthesized and characterized by means of DTA, 81Br NQR, 6Li, 7Li, 23Na, and 115In NMR, and AC conductivity. These measurements revealed the presence of phase transitions and cationic diffusion in both compounds. From the spin-lattice relaxation times of 81Br NQR and the peak widths of 7Li and 23Na NMR spectra, it is deduced that the conduction is due to cationic diffusion. The activity energy for the Li+ diffusion was found to be 24 kJ/mol for Li3InBr6 .
