“…Display technologies must be able to render a large range of visible wavelengths and as such require individual red, green and blue (RGB) pixels. Fortunately, there are an abundance of polymers that emit (and absorb) in the visible range, with band gap energies between 1-4 eV [7], meaning this is also a straightforward task.…”

We present recent progress on visible light communication systems using polymer light-emitting diodes as the transmitters and a commercial silicon photodetector as the receiver. In this work we use transmitters at red, green and blue wavelengths to investigate the maximum on-off keying link performance of each device type as the first steps towards a wavelength-division multiplexed link. We show that a total transmission speed of 13 Mb/s is achievable when considering the raw bandwidth of each of the RGB PLEDs. Such a rate represents a 30% gain over previously demonstrated systems. Further capacity improvement can be achieved using high performance artificial neural network equalizer offering a realistic prospect for transmission speeds up to 54.9 Mb/s.

“…These dependences on the ODA vapor treatment time show that the swelling of the Azo-PAA film is almost completed in the first hour, and the swelling ratio is saturated at ∼300%. This saturation behavior suggests that the swelling is promoted by salt formation of polyamic acid and ODA [22]. The swelling is probably limited by the number of carboxylic acid groups in the Azo-PAA film.…”

One‐Pot Synthesis of Sulfur and Nitrogen Co‐Functionalized Graphene Material using Deep Eutectic Solvents for Supercapacitors

et al. 2019

A green approach to the synthesis of sulfur and nitrogen co‐functionalized reduced graphene oxide (SN‐rGO) is presented; it involves the reduction of graphene oxide (GO) using a deep eutectic solvent (DES) as chemical reducing agent and dopant. For the first time, a DES of choline chloride and sodium sulfide comprising cheap and safe components is introduced, and is both highly effective and reusable as a reducing agent for the production of SN‐rGO. The DES is utilized as a solvent as well as reducing agent and dopant to generate SN‐rGO. This DES is highly efficient in removing oxygen functionalities from GO and for subsequent sulfur and nitrogen functionalization for high energy‐storage efficiency. The reduction ability of this DES is confirmed with five consecutive cycles, which adds to its sustainability and recyclability in the development of energy‐storage devices. SN‐rGO exhibits a high specific capacitance of 509 F g−1 at 1 A g−1, which corresponds to high energy and power densities of 57.3 Wh kg−1 and 1804.7 W kg−1, respectively. This simple and green method for direct reduction of GO with sulfur and nitrogen functionalization on the graphene surface can provide cost‐effective bulk production of a nanocarbon template for energy storage applications.
