We demonstrate the fabrication of organic light-emitting diodes (OLED) with various emission colours by blending and/or doping the polymer host matrix with different dopants. We firstly present the preparation of elementary OLEDs i.e. blue, green, orange, and cool white diodes. Then, we exhibit the fabrication of light-emitting devices with particular emission colours such as magenta, red, and warm white electroluminescence. Blue emission from polyfluorene (PFO), green emission from polyfluorene-alt-benzothiadiazole (F8BT), and orange emission from polyphenylene-vinylene (MEH-PPV), together with the red emission from Lumogen F Red have been mixed in different combination to vary the emission colour in OLEDs.
Keywords: OLED, white organic light-emitting diode, polyfluorene, blending/doping, solid-state lighting
