Abstract
We report the enhancement of the optical second harmonic signal in non-centrosymmetric semiconductor CdS quantum dots, when they are placed in close contact with isolated silver nanoparticles. The intensity enhancement is about 1000. We also show that the enhancement increases when the incoming laser frequency is tuned toward the spectral position of the silver plasmon at , proving that the silver nanoparticle modifies the nonlinear emission.

我们报道了当非中心对称半导体CdS量子点与孤立的银纳米粒子密切接触时，光学二次谐波信号的增强。强度增强约1000。我们还发现，当入射激光频率向银等离子体激元的光谱位置调谐时，增强效应增加，证明纳米银粒子改变了非线性发射。收稿日期:2011年3月8日，收稿日期:2011年5月30日;编辑:L. Vina;评审人:R. Gordon，加拿大不列颠哥伦比亚省维多利亚大学电气与计算机工程系;DOI: 10.4279 / PIP.030002引用自:P. M. Jais, C. von Bilderling, A. V. Bragas，《物理学报》3,030002 (2011)
期刊介绍：
Papers in Physics publishes original research in all areas of physics and its interface with other subjects. The scope includes, but is not limited to, physics of particles and fields, condensed matter, relativity and gravitation, nuclear physics, physics of fluids, biophysics, econophysics, chemical physics, statistical mechanics, soft condensed matter, materials science, mathematical physics and general physics. Contributions in the areas of foundations of physics, history of physics and physics education are not considered for publication. Articles published in Papers in Physics contain substantial new results and ideas that advance the state of physics in a non-trivial way. Articles are strictly reviewed by specialists prior to publication. Papers in Physics highlights outstanding articles published in the journal through the Editors'' choice section. Papers in Physics offers two distinct editorial treatments to articles from which authors can choose. In Traditional Review, manuscripts are submitted to anonymous reviewers seeking constructive criticism and editors make a decision on whether publication is appropriate. In Open Review, manuscripts are sent to reviewers. If the paper is considered original and technically sound, the article, the reviewer''s comments and the author''s reply are published alongside the names of all involved. This way, Papers in Physics promotes the open discussion of controversies among specialists that are of help to the reader and to the transparency of the editorial process. Moreover, our reviewers receive their due recognition by publishing a recorded citable report. Papers in Physics publishes Commentaries from the reviewer(s) if major disagreements remain after exchange with the authors or if a different insight proposed is considered valuable for the readers.
