A Standardized Light-Emitting Diode Device for Photoimmunotherapy

Low-power flexible organic light-emitting diode display device.

Josephson light-emitting diode.

We consider an optical quantum dot where an electron level and a hole level are coupled to respective superconducting leads. We find that electrons and holes recombine producing photons at discrete energies as well as a continuous tail. Further, the spectral lines directly probe the induced superconducting correlations on the dot. At energies close to the applied bias voltage eV(sd), a paramete...

Transflective device with a transparent organic light-emitting diode and a reflective liquid-crystal device

Tien-Lung Chiu (SID Student Member) Haiqing Xianyu (SID Member) Zhibing Ge Jiun-Haw Lee (SID Member) Kou-Chen Liu Shin-Tson Wu (SID Fellow) Abstract — A high-transmittance transflective device based on a hybrid structure consisting of a transparent organic light-emitting diode (OLED) stacked on top of a reflective liquid-crystal device (RLCD) was conceptually demonstrated. By placing the transp...

Resonant cavity light-emitting diode

A novel concept of a light-emitting diode (LED) is proposed and demonstrated in which the active region of the device is placed in a resonant optical cavity. As a consequence, the optical emission from the active region is restricted to the modes of the cavity. Resonant cavity light-emitting diodes (RCLED) have higher spectral purity and higher emission intensity as compared to conventional lig...
