Deep-UV Liquid Immersion Mastering of High Density Optical Discs

Highly efficient near ultraviolet organic light-emitting diode based on a meta-linked donor–acceptor molecule

“…Near ultraviolet (NUV) emitting materials have attracted considerable attention because of their wide applications in the fields of chemical and biological sensors, 1 high-density information storage, 2 and lighting sources. 3 Furthermore, NUV emitting materials can also be utilized as host materials in doped organic light-emitting diodes (OLEDs), aiming at suppressing the aggregation- or concentration-caused luminescence quenching of fluorescent and phosphorescent emitters.…”

Giant Enhancement of External Quantum Efficiency in Near‐UV Organic Light‐Emitting Diodes via Device Aging and Impedance Spectroscopy Analysis

“…A UV organic light-emitting diode (UV OLED) with flexibility, low cost, and scalable manufacturing considerably broadens short-wavelength applications of an organic electronic device in exciting lighting source, chemical sensor, bioanalytical, and high-density information storage. [1][2][3][4][5][6] State-of-the-art research has mainly focused on tailoring the cathode/anode interface to achieve satisfactory carrier balance in the emissive layer, owing to the relatively wide bandgap of UV fluorescent molecules. [7,8] External quantum efficiency (EQE), the most important electro-optical parameter of UV OLEDs, has been increased from 0.1% [7] to 4.6% [8] for conventional fluorescent molecules and has recently achieved 9.3% [9] with the use of thermally activated delayed fluorescent material.…”
