Fine Characteristics Tailoring of Organic and Inorganic Nanowires Using Focused Electron‐Beam Irradiation

Abstract

Minileuchtdrähte: Lichtemittierende organische und anorganische Nanodrähte (NWs) aus Poly(3‐methylthiophen) (P3MT) bzw. Titandioxid zeigen nach Behandlung mit fokussierten Elektronenstrahlen multiple, eindimensionale, serielle Kompartimente (siehe Bild), die Übergitter‐NWs ähneln und Anwendung für lichtemittierende Farbstrichcode‐NWs finden könnten. Ihre strukturellen, optischen und elektrischen Eigenschaften lassen sich durch die Bestrahlungsbedingungen steuern.

Fine Control of Photoluminescence and Optical Waveguiding Characteristics of Organic Rubrene Nanorods Using Focused Electron-Beam Irradiation

“…The results here are different from the previous results of other organic crystals. , Hong et al reported the variation of steady-state LCM PL efficiency of organic nanowires by the focused E-beam treatment with various doses . Takazawa and co-workers reported efficient PL waveguiding using the organic dye with H-aggregation, in which the optical signals at a specific wavelength were propagated without loss (∼250 μm) .…”

“…26,42 Hong et al reported the variation of steadystate LCM PL efficiency of organic nanowires by the focused Ebeam treatment with various doses. 26 Takazawa and co-workers reported efficient PL waveguiding using the organic dye with Haggregation, in which the optical signals at a specific wavelength were propagated without loss (∼250 μm). 42 Even though the propagation distance in this study was ∼25 μm due to the length limit of the rubrene NR, our results such as the use of the focused E-beam can be applied to both organic crystals and nanostructures for the fine control of dynamic optical waveguiding characteristics.…”

“…The fine control of the optical and electrical characteristics of organic and inorganic nanostructures is also an important research direction for nanoscale optoelectronics and photonics. , Electron-beam (E-beam) and proton-beam irradiations on predetermined positions of target materials induce defects and lattice-mismatches, modulating the materials’ intrinsic properties. , Recently, Hong et al reported on the nanoscale control of the photoluminescence (PL) efficiency of organic and inorganic nanostructures through focused E-beam treatments. , Modulation of the optical properties of inorganic c-SiO 2 with ion-beam irradiation has also been studied by Mansano-Santamaria et al The fine control of photonic dynamic characteristics, such as optical waveguiding, for crystalline organic semiconducting nanostructures can be performed through focused E-beam irradiation for applications to new photonic integration, optoelectronic communication, and miniaturized optical sensors. Organic semiconducting crystals and nanostructures showed anisotropic electrical and optical properties. ,, Therefore, the crystalline structure and the interaction between the material and focused E-beam should be investigated.…”
