China Nanomaterial Buy Gold Nanowires AuNWs Used for Organic light emitting devices

Research shows that Au gold Nanowires can enhance the light-emitting efficiency of organic LEDs by up to 45%, an added bonus is that the Au gold nanowires could replace expensive indium tin oxide as the anode of the devices. The technique might even be applied to liquid crystal displays to increase their brightness and possibly eliminate the need for colour filters.


An array of 5nm thick gold nanowires placed on top of an indium tin oxide (ITO) anode can increase the light-emitting intensity of an OLED made from Alq3 by up to two times. The nanowires, which act as light scatterers, are placed 450 nm apart in the arrays. This period matches the peak emission wavelength of the emitted light, which enhances light extraction.


Organic light emitting devices (OLEDs) are promising for next-generation displays and lighting.the gold nanowire arrays might be used to replace expensive ITO in OLEDS because they are conducting and have a high optical transmission.
