Nano-Engineering Versatile Core-Shell Nanoplatforms for Tuning Enhanced Opto-electronic Matter Interactions

In this communication, it is presented the concept of optics based on Core-shell architectures controlling the nanoscale and beyond. It is demonstrated how these types of architectures can be designed, from prototyping to synthesis, using colloidal and laser-based techniques. This particular nanoarchitecture was presented as a fundamental structure that can be tuned as needed through the use of various materials, enabling control over size, shape, and topological features. Then, the impact of Core-shell nanoarchitecture to tune photon and electron matter interactions to enhance physics and chemistry with perspectives of non-classical light generation is shown. Therefore, fundamental wet chemistry to advanced nano-optics studies by the use of Core-shell nanoplatforms is discussed. In this regard, varied phenomena such as enhanced and amplified approaches are presented. Enhanced based techniques such as metal-enhanced fluorescence (MEF), phosphorescence (MEP), enhanced quantum phenomena (EQ), and amplified signaling are of interest. In this context, the control of nanoarchitecture should be accurately controlled to place the different optical components. Optical active materials are varied to tune photon matter interactions accompanied by the generation of new modes of energies. These emerging non-classical light pathways involve strong electromagnetic field interactions, which significantly influence the electronic and optical properties of all participating materials. Moreover, photonics pathways could be modified to stabilize the excited state, increase quantum yields, and improve performances. In this context, the tuning of high-intense electromagnetic fields related with plasmonics and pseudo-electromagnetics from other semiconductors such as carbon-based materials was presented. Thus, targeted enhanced nano-emitters are presented and highlighted in this article; however, further discussion towards enhanced optics is discussed. In this manner, highlights from the nanoscale to far-field optical studies and applications are opened. So, Core-shell nanoarchitectures are presented as important optical nanoplatforms with high impact within varied optical set-ups.
