Efficient and mechanically robust stretchable organic light-emitting devices by a laser-programmable buckling process
Stretchable organic light-emitting devices are becoming increasingly important in the fast-growing fields of wearable displays, biomedical devices and health-monitoring technology. Although highly stretchable devices have been demonstrated, their luminous efficiency and mechanical stability remain impractical for the purposes of real-life applications. This is due to significant challenges aris...
متن کاملEfficient green coumarin dopants for organic light-emitting devices.
We have synthesized a new green fluorescent dopant C-545P having incorporated five strategically placed "methyl" steric spacers on the julolidyl ring system. C-545P has good thermal properties and photostability, and when fabricated as a dopant in an Alq(3)-hosted OLED device, it shows notable improvement in luminance efficiency and is more resistant to concentration quenching than C-545T, part...
متن کاملOrganic Light Emitting Diodes: Devices and applications
Opto-electronic devices using organic materials are becoming widely desirable for manifold reasons [1-4]. In fact, organic devices have the potential for cost advantages over inorganic devices. In addition, inherent properties of organic materials, such as their flexibility make them well suited for particular applications such as fabrication on a flexible substrate. The materials used in organ...
متن کاملA single-molecule excimer-emitting compound for highly efficient fluorescent organic light-emitting devices.
A pyrene-containing single-molecule excimer-emitting compound, 1,8-bis(pyren-2-yl)naphthalene (BPyN), was synthesized. With BPyN as a host emitter, C545T-based green OLEDs were fabricated, exhibiting high efficiencies of 22 lm W(-1), 22 cd A(-1) and 6.2% external quantum efficiency (EQE) at 100 cd m(-2), and 19 lm W(-1), 22 cd A(-1) and 6.2% EQE at 1000 cd m(-2).
متن کاملNanoimprinted organic semiconductor laser pumped by a light-emitting diode.
An organic semiconductor laser, simply fabricated by UV-nanoimprint lithography (UV-NIL), that is pumped with a pulsed InGaN LED is demonstrated. Molecular weight optimization of the polymer gain medium on a nanoimprinted polymer distributed feedback resonator enables the lowest reported UV-NIL laser threshold density of 770 W cm(-2) , establishing the potential for scalable organic laser fabri...
