关于“产生非常窄的等离子体线型的银纳米颗粒阵列结构”的评论[J. Chem. Phys. 120，10871（2004）]
Comment on "Silver nanoparticle array structures that produce remarkably narrow plasmon lineshapes" [J. Chem. Phys. 120, 10871 (2004)]
摘要：
在这篇评论中，我讨论了Zou，Janel和Schatz（ZJS）的论文“Silver nanoparticle array structures that produce extremely narrow plasmon line shapes”[J.Chem.Phys.120，10871（2004）]中的两个错误陈述。第一个陈述是关于准静态近似在我早期关于类似主题的工作中的使用，第二个陈述涉及纳米颗粒周期链中辐射弛豫的精确消除的可能性。阐明了准静态近似、偶极子近似和ZJS所采用的Doyle近似[Phys.Rev.B39，9852（1989）]之间的关系。结果表明，辐射弛豫的精确抵消不能发生在特定的几何考虑ZJS。
英文摘要：
In this Comment I discuss two incorrect statements which were made in the paper "Silver nanoparticle array structures that produce remarkably narrow plasmon line shapes" [J. Chem. Phys.120, 10871 (2004)] by Zou, Janel, and Schatz (ZJS). The first statement is about the use of quasistatic approximation in my earlier work on the similar subject, and the second statement concerns the possibility of exact cancellation of radiative relaxation in periodical chains of nanoparticles. The relationship between the quasistatic approximation, the dipole approximation, and the approximation due to Doyle [Phys. Rev. B39, 9852 (1989)] which was used by ZJS is clarified. It is shown that the exact cancellation of radiative relaxation cannot take place in the particular geometry considered by ZJS.
