Abstract

In this paper, La2O3 doped with varied Ce3+ concentrations were synthesized via hydrothermal co-precipitation followed by high temperature calcined process in H-2/N-2 atmosphere. Three new peaks show up at 698, 650 and 558 in O-17 solid state NMR spectra due to Ce3+ doping. The intensies of these peaks increase with Ce3+ concentration. According to the resonant frequencies and the intensities, the peaks at around 698 and 650, and 558 are assigned to four-coordinated OCeLa3 and six-coordinated OCeLa5 species, respectively. The results show that O-17 solid-state NMR spectroscopy can be used to study rare earth doped oxides for applicable functional materials.

Ce3+掺杂La2O3的O-17固体核磁共振研究

本文在H-2/N-2气氛下，采用水热共沉淀法和高温煅烧法合成了掺杂不同Ce3+浓度的La2O3。由于Ce3+的掺杂，在O-17固体核磁共振谱中出现了698、650和558三个新峰。这些峰的强度随着Ce3+浓度的增加而增加。根据共振频率和强度，698、650和558附近的峰值分别属于四协调OCeLa3和六协调OCeLa5物种。结果表明，O-17固体核磁共振光谱可以用于研究稀土掺杂氧化物的适用功能材料。
