چکیده
Abstract The size‐ and shape‐dependent localized surface plasmon properties of metallic nanoparticles (NPs) enable nanoscale‐enhanced near‐field applications in a wide range fields, including spectroscopy, nonlinear optics, sensing. Orderly assembled NPs can construct plasmonic metamaterials for light manipulation at subwavelength scale, exhibiting new collective resonant modes regulated by coupling between their fundamental components. Despite the recognition its significant advantages photonics integration, plasmonic‐based tailored optical responses practical have remained elusive due to limitations scaling up processes, as neither etching nor assembly design fabricate embedded devices into functional devices/structures. Here, is demonstrated ultrafast laser‐induced writing‐on‐demand inside solids, tailoring distribution sizes. By controlling laser scanning speed, situ redistribution observed. Plasmon mediated local energy deposition considered main mechanism driving nano‐patterning range. A direct nano‐printing realized utilizing response laser‐modified NP structures/patterns. This work paves way directly induced composite structures transparent materials well‐defined controlled depth applications.

15 صفحه اولsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...
متن کاملQuantum-Spillover-Enhanced Surface-Plasmonic Absorption at the Interface of Silver and High-Index Dielectrics.
We demonstrate an unexpectedly strong surface-plasmonic absorption at the interface of silver and high-index dielectrics based on electron and photon spectroscopy. The measured bandwidth and intensity of absorption deviate significantly from the classical theory. Our density-functional calculation well predicts the occurrence of this phenomenon. It reveals that due to the low metal-to-dielectri...
