Light Converting Inorganic Phosphors for White Light-Emitting Diodes
White light-emitting diodes (WLEDs) have matched the emission efficiency of florescent lights and will rapidly spread as light source for homes and offices in the next 5 to 10 years. WLEDs provide a light element having a semiconductor light emitting layer (blue or near-ultraviolet (nUV) LEDs) and photoluminescence phosphors. These solidstate LED lamps, rather than organic light emitting diode ...
متن کاملNovel Design of Iridium Phosphors with Pyridinylphosphinate Ligands for High-Efficiency Blue Organic Light-emitting Diodes
Due to the high quantum efficiency and wide scope of emission colors, iridium (Ir) (III) complexes have been widely applied as guest materials for OLEDs (organic light-emitting diodes). Contrary to well-developed Ir(III)-based red and green phosphorescent complexes, the efficient blue emitters are rare reported. Like the development of the LED, the absence of efficient and stable blue materials...
متن کاملNovel rare-earth-free yellow Ca5Zn3.92In0.08(V0.99Ta0.01O4)6 phosphors for dazzling white light-emitting diodes
White light-emitting diode (WLED) products currently available on the market are based on the blue LED combined with yellow phosphor approach. However, these WLEDs are still insufficient for general illumination and flat panel display (FPD) applications because of their low color-rendering index (CRI < 75) and high correlated color temperature (CCT = 6000 K). Although near-ultraviolet (UV) LED ...
متن کاملRed Phosphorescent Organic Light-emitting Diodes
Phosphorescent organic light-emitting diodes (OLEDs) have the great advantage of highlyefficient emission compared with conventional fluorescent OLEDs. Pt(II) porphyrins are among the most promising saturated red phosphorescent dyes, yet tuning of their properties by making structural modifications has only been attempted on a modest scale, despite the large structuraldiversity of synthetic por...
