Electricity−free electroluminescence excited by droplet impact driven triboelectric field on Solid−Liquid interface

, 2020
In this work, a novel solid-liquid interfacing triboelectric field based electroluminescence (SL-TEL) was proposed. When a droplet impacting on the SL-TEL device surface, specific textured green SL-TEL emit on the two cross-overlapped areas.

Organic electroluminescent diodes

Applied Physics Letters, 1987
A novel electroluminescent device is constructed using organic materials as the emitting elements. The diode has a double-layer structure of organic thin films, prepared by vapor deposition. Efficient injection of holes and electrons is provided from an indium-tin-oxide anode and an alloyed Mg:Ag cathode.

Novel 9,9-dimethylfluorene-bridged D–π–A-type fluorophores with a hybridized local and charge-transfer excited state for deep-blue electroluminescence with CIEy ∼ 0.05

Journal of Materials Chemistry C, 2019
Deep-blue electroluminescence with a maximum EQE of 5.74% and CIEy ∼ 0.05 is achieved based on a newly designed D–π–A fluorophore with a HLCT excited state.

Electroluminescence

Electroanalysis, 1991
AbstractA definition of electrogenerated luminescence (ECL) is given. Chemiluminescent reactions of different kinds are cited, as well as various types of pathway to the formation of the emitting excited state. After a consideration of the energetic and kinetic requirements for ECL‐producing reactions, the experimental conditions are examined.

Electroluminescence of Giant Stretchability

Advanced Materials, 2015
A new type of electroluminescent device achieves giant stretchability by integrating electronic and ionic components. The device uses phosphor powders as electroluminescent materials, and hydrogels as stretchable and transparent ionic conductors. Subject to cyclic voltage, the phosphor powders luminesce, but the ionic conductors do not electrolyze. The

ORGANIC ELECTROLUMINESCENCE DISPLAYS

International Journal of High Speed Electronics and Systems, 1997
Recently, organic light emitting diodes have received a lot of attention in different research laboratories world-wide. Red, green and blue emitting devices are readily available. Devices with luminous efficiencies greater than 15 lm/W and lifetimes longer than 10,000 hours have been demonstrated.

Principle and application of inorganic Electroluminescence and organic Electroluminescence

2011 International Conference on Electric Information and Control Engineering, 2011
Eelectroluminescence is a solid light. Based on the different structure and working principle, Electroluminescence (EL) can be divided into inorganic electroluminescence and organic electroluminescence. In this paper some rresearches on electroluminescence are reviewed.

Electroluminescence

2012
AbstractElectroluminescence of inorganic semiconductors, as one of the principal application directions of luminescence phenomena, is treated in detail. At first, a short historical note is given. Two basic types of electroluminescence are distinguished: High-field electroluminescence and injection electroluminescence.
