Since the modulation transfer function and the limiting resolution decrease monotonically with layer thickness, a compromise between X-ray ...
Phosphors for White LEDs SpringerLink
A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy. The term is used both for fluorescent or phosphorescent substances which glow on exposure to ultraviolet or visible light, and cathodoluminescent substances which glow … See more The scintillation process in inorganic materials is due to the electronic band structure found in the crystals. An incoming particle can excite an electron from the valence band to either the conduction band or the See more Many phosphors tend to lose efficiency gradually by several mechanisms. The activators can undergo change of valence (usually oxidation), the crystal lattice degrades, atoms – … See more Various Some other phosphors commercially available, for use as X-ray screens, neutron detectors, alpha particle scintillators, etc., are: See more • Cathodoluminescence • Laser • Luminophore See more Phosphors are usually made from a suitable host material with an added activator. The best known type is a copper-activated zinc sulfide (ZnS) and the silver-activated zinc sulfide (zinc sulfide silver). The host materials … See more Lighting Phosphor layers provide most of the light produced by fluorescent lamps, and are also used to improve the balance of light produced by metal halide lamps. Various neon signs use phosphor layers to produce different colors of … See more • Arunachalam Lakshmanan (2008). Luminescence and Display Phosphors: Phenomena and Applications. Nova Publishers.

WebFeb 18, 2024 · To enhance efficiency and decrease WOLED roll-off, complicated doping technologies are employed, which result in an additional increase in costs. Herein, a deep-blue-light molecule (3TPA-CN) with aggregation-induced emission (AIE) is introduced as blue emitter and phosphor host to fabricate WOLEDs. WebOct 22, 2024 · Here, we merge a support vector machine regression model to predict a phosphor host crystal structure’s Debye temperature, which is a proxy for photoluminescent quantum yield, with high-throughput density functional theory calculations to evaluate the… View on Springer nature.com Save to Library Create Alert Cite 159 Citations Citation Type shanghai mccoy quotes
