金属基底上金属纳米颗粒间隙内的自发辐射调控
|
摘要
将聚甲基丙烯酸甲酯(PMMA)层置于金纳米颗粒与金基底之间,研究了金纳米颗粒对处于PMMA夹层中的分子或量子点辐射源的总辐射速率、远场辐射速率、辐射方向等的影响。与单个金纳米颗粒相比,当2,3,5,9个金纳米颗粒等间距排列时,总辐射速率和远场辐射速率都会增强。通过测量远场辐射方向,可以反推出纳米颗粒的数量和间距,从而实现纳米颗粒数量和间距的高精度测量。
When the polymethyl methacrylate(PMMA)layer is placed between the gold nanoparticles and gold substrate,we study the effects of metal nanoparticles on the total emission rates and radiative emission rates and far-field radiation pattern of the radiation source of molecular or quantum dots in the PMMA layer.Compared with single gold nanoparticle,when two,three,five and nine gold nanoparticles are put on the PMMA layer with the same distance,the total radiation rates and radiative emission rates are enhanced.By measuring the far-field radiation pattern,the number of nanoparticles and the distance between nanoparticles can be inversely deduced,thus realizing the high precision measurement of nanoparticles.
