TL;DR: In this article, the surface plasmon resonance effect of carbon-dot-supported silver nanoparticles (CD-Ag nanoparticles) was used as reducing agent and template to fabricate solution-processable polymer light-emitting diodes and polymer solar cells.

TL;DR: This work exemplifies how the functionality of metal halide perovskites is extremely sensitive to the nature of the (nano)crystalline surface and presents a route through which to control the formation and migration of surface defects to achieve bandgap stability for light emission and could also have a broader impact on other optoelectronic applications-such as photovoltaics-for which band gap stability is required.

TL;DR: Workfunction-tunable, highly conductive, N-doped reduced graphene film is demonstrated, which is obtainable from the spin-casting of graphene oxide dispersion and can be successfully employed as a transparent cathode for high-performance polymer light-emitting diodes (PLEDs) as an alternative to fluorine- doped tin oxide (FTO).

TL;DR: A new hetero-PBG structure consisting of an anisotropic nematic layer sandwiched between two cholesteric liquid-crystal layers with different helical pitches is reported, displaying the optical diode performance: that is, the non-reciprocal transmission of circular polarized light at the photonic-bandgap regions.

TL;DR: B Balanced charge injection and transport are a basic requirement for highly effi cient optoelectronic devices and poor electron injection continues to be a serious problem for realizing highly effI cient PLEDs.
