Improved optoelectronic characteristics of light-emitting diodes by using a dehydrated nanotube titanic acid (DNTA)-polymer nanocomposite
Article Abstract:
P-type dehydrated nanotube titanic acid (DNTA) can significantly enhance hole injection and transport in holes-only transport devices. Through fabricated and characterized organic light-emitting diodes (OLEDs) and by using a DNTA-poly(vinylcarbazole) (PVK) nanocomposite as the hole transport layer, it was found that the performance of these devices was greatly improved with a higher luminance, and enhanced efficiency, and a lower turn-on voltage.

Molecularly thin polymer films that function to enhance charge injection efficiency in organic light-emitting diodes
Article Abstract:
Layer-by-layer (LbL) multilayer films of monomethyl maleate copolymers with styrene (P1) or vinyl carbazole (P2) are fabricated on oxidized surfaces. Results reveal that the modified indium-tin oxide (ITO) electrodes with P2 multilayers could effectively reduce the hole injection barrier at the ITO/TPD interfaces, unlike the case of the insulating P1 multilayers.
