X-ray and ultra-violet photoemission spectra have been measured to study the valence-band structures of piperidinium trihaloplumbates C 5 H 10 NH 2 PbX 3 [X = I, Br], which have natural nano-scale one-dimensional structures. The valence-band spectra of lead halides, which have the three-dimensional structures, are also reported for comparison. The partial densities of states related to the constituent
已测量 X 射线和紫外光发射光谱以研究具有天然纳米级一维结构的
哌啶鎓三卤化
铅 C 5 H 10 NH 2 PbX 3 [X = I, Br] 的价带结构。还报告了具有三维结构的卤化
铅的价带光谱以供比较。通过 XPS 和
UPS 之间的比较,获得了与组成离子和分子相关的状态的部分密度。还进行了经验 LCAO 计算以分析实验结果。提出了 C 5 H 10 NH 2 PbX 3 [X = I, Br] 中的类量子阱电子结构。
