Centrifugal Force Boosts Self‐Assembly of Gradient Lattice Photonic Crystals
Advanced Photonics ResearchGradient photonic crystals, compared to traditional photonic crystals, possess broader photonic bandgaps and more flexible arrangement structures. This article proposes a centrifugal force‐driven self‐assembly method for controllable construction of ...

Design and characterisation of photonic quasicrystals from microwave to optical regime
, 2010 Photonic band-gap materials are artificially periodic engineered materials with which we can control and manipulate the electromagnetic radiation. The period photonic crystals are well known and have been studied for the last two decades.

Advanced Materials, EarlyView.We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Characterization of photonic structures using visible and infrared polarimetry
EPJ Web of Conferences, 2010 Photonic Crystals are materials with a spatial periodic variation of the refractive index on the wavelength scale. This confers these materials interesting photonic properties such as the existence of photonic bands and forbidden photon frequency ...

Role of the Recombination Zone in Organic Light‐Emitting Devices
Advanced Materials, EarlyView.This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency
Advanced Materials, EarlyView.This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.
