“…To fabricate ultraflexible OLEDs, transparent TFC electrodes are required. The reported electrodes utilized in flexible OLEDs are mainly based on PEDOT [173], CNT [44,174], Ag NWs/grids [175][176][177][178][179], graphene [45,180], ITO [76], and metal oxide [181]. For achieving higher efficiency, top-emitting architectures [182][183][184][185] and nanostructured/scattered electrodes or substrates [47,[130][131][132][133][134][135] can be adopted, to enhance output coupling or light extraction of the devices.…”

Flexible thin-film organic semiconductor devices have received wide attention due to favorable properties such as light-weight, flexibility, reproducible semiconductor resources, easy tuning of functional properties via molecular tailoring, and low cost large-area solution-procession. Among them, ultraflexible electronics, usually with minimum bending radius of less than 1 mm, are essential for the development of epidermal and bio-implanted electronics, wearable electronics, collapsible and portable electronics, three dimensional (3D) surface compliable electronics, and bionics. This review firstly gives a brief introduction of development from flexible to ultraflexible organic semiconductor electronics, and design of ultraflexible devices, then summarizes the recent advances in ultraflexible thin-film organic semiconductor devices, focusing on organic field effect transistors, organic light-emitting diodes, organic solar cells and organic memory devices.

“…Due to its wide band gap (3.6 eV), zinc sulfide (ZnS) is a potential optoelectronic material, which is suitable for the applications in light-emitting diodes, short wavelength emitting laser diodes and photodetectors [1][2][3]. Recently, a considerable amount of work has been devoted to incorporating transition metal ions into ZnS nanomaterials to improve or modify their structural and optical performances.…”

“…Organic light-emitting diodes (OLEDs) are well known for offering an outstanding variety in device form factor: they can be built on plastic films or metal foils and thus can be ultrathin and flexible [1][2][3][4]; they can be designed to emit light in a broad range of colors [5][6][7]; and most noticeably they can be made transparent by using transparent electrodes for both anode and cathode [8][9][10]. This transparency feature is considered to be among the key factors that distinguish OLEDs from other light-emitting devices.…”

We report a study on transparent organic light-emitting diodes (OLEDs) with different bidirectional emission colors, enabled by color-conversion organic capping layers. Starting from a transparent blue OLED with an uncapped Ag top electrode exhibiting an average transmittance of 33.9%, a 4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM)-doped tris-(8-hydroxy-quinolinato)-aluminium (Alq3) capping layer is applied to achieve color-conversion from blue to orange-red on the top side while maintaining almost unchanged device transmittance. This color-conversion capping layer does not only change the color of the top side emission, but also enhances the overall device efficiency due to the optical interaction of the capping layer with the primary blue transparent OLED. Top white emission from the transparent bi-directional OLED exhibits a correlated color temperature around 6,000K-7,000K, with excellent color stability as evidenced by an extremely small
