Light-emitting diode physics

Light-emitting diodes (LEDs) produce light (or infrared radiation) by the recombination of electrons and electron holes in a semiconductor, a process called "electroluminescence".The wavelength of the light produced depends on the energy band gap of the semiconductors used. Since these materials have a high index of refraction, [note 1] design features of the devices such as

Metal–Organic Phase-Change Materials for Thermal Energy Storage

The development of materials that reversibly store high densities of thermal energy is critical to the more efficient and sustainable utilization of energy. Herein, we investigate metal–organic compounds as a new class of solid–liquid phase-change materials (PCMs) for thermal energy storage. Specifically, we show that isostructural series of divalent metal amide

Tuning mechanoluminescent long-afterglow composites toward

Mechanoluminescence (ML) and long-afterglow (LAG) luminescence are usually studied independently and applied in different fields. SrAl2O4:Eu(II)/Dy(III) (SAOED) is a well-known long-afterglow and elastico-mechanoluminescent material that emits bright green visible light through absorption of photon energy, followed by naturally thermal release or

Review Active luminous road markings: A comprehensive review

The exposure time affects the energy storage of PPRMs. PPRMs cannot be fully excited with a short exposure time. With the extension of the illumination time, more energy is absorbed by the ground state electrons, and the defect level of the phosphorescent materials is gradually saturated. The afterglow intensity reaches the best level.
