简介：高贵金属性的nanostructures展览专辑光性质源于表面电浆子的刺激。在各种各样的金属性的nanostructures之中，因为他们的唯一、吸引人的形状依赖者plasmonic性质，nanorods吸引了特别注意。Nanorods能支持横向、纵的电浆子模式，后者一强烈取决于nanorod的方面比率。这些模式能习惯性地被调节从对可见在红外线附近光谱区域。尽管nanorods广泛地被调查了，有很少研究，奉献给从nanorod形状背离的nanostructures。这评论在二种新奇quasi-one-dimensional银nanostructures，nanorice和nanocarrot的开发提供最近的进步的概述，包括他们在察觉到应用程序的plasmonic的综合体，水晶的描述，plasmonic性质分析，和性能。
