An Organic White Light-Emitting Fluorophore

Strategies to Achieve High-Performance White Organic Light-Emitting Diodes

As one of the most promising technologies for next-generation lighting and displays, white organic light-emitting diodes (WOLEDs) have received enormous worldwide interest due to their outstanding properties, including high efficiency, bright luminance, wide viewing angle, fast switching, lower power consumption, ultralight and ultrathin characteristics, and flexibility. In this invited review,...

Harvesting Emission in White Organic Light Emitting Devices

Effect of Interlayer on White Phosphorescent Organic Light-emitting Devices

We demonstrated a novel white electrophosphorescent organic light emitting diodes (PHOLEDs), which structure was ITO/NPB (35 nm)/MCP (5 nm)/Firpic: MCP 10 wt% (15 nm)/ Ir (MDQ)2(acac): TPBI X wt% (2 nm)/Firpic:TPBI 10 wt% (10 nm)/TPBI (40 nm)/LiF (1 nm)/Al (100 nm). The luminescent properties were studied by inserting different doping concentration of the red emitting layer (Ir(MDQ)2(acac):TPBI...

Colour tuning in white hybrid inorganic/organic light-emitting diodes

White hybrid inorganic/organic light-emitting diodes (LEDs) were fabricated by combining a novel organic colour converter with a blue inorganic LED. An organic small molecule was specifically synthesised to act as down-converter. The characteristics of the white colour were controlled by changing the concentration of the organic molecule based on the BODIPY unit, which was embedded in a transpa...

An electrophosphorescent organic light emitting concentrator

We demonstrate threefold directional light concentration from an organic light-emitting diode luminaire for use in spot lighting and other applications where high intensity illumination is required. The concentrating luminaire comprises four triangular, large-area green electrophosphorescent organic light emitting diodes (PHOLEDs) deposited on plastic substrates and assembled into a pyramidal s...
