second harmonic Nd:YAG laser in the presence of oxygen molecules in argon/nitrogen matrices. The major species obtained in the Ar matrix were Te2O2, TeO2, Te2O4 and the minor species were TeO, Te2O and TeO3. In N2 matrix, in addition to the above primary ablation products, reaction products TeN and Te2N were also observed. The structure, energies and the vibrational frequencies of different tellurium oxide
摘要 在氩/氮基质中存在氧分子的情况下,使用二次谐波 Nd:YAG 激光对碲进行激光烧蚀。在 Ar 基质中获得的主要物质是 Te2O2、TeO2、Te2O4,次要物质是 TeO、Te2O 和 TeO3。在 N2 基体中,除了上述初级烧蚀产物外,还观察到反应产物 TeN 和 Te2N。不同碲氧化物和氮化物种类的结构、能量和振动频率是使用 DFT 计算进行的。计算出的振动频率与实验频率相证实。
