Promotional effect of silver nanoparticle embedded Ga-Zr-codoped TiO₂ as an alternative anode for efficient blue, green and red PHOLEDs.

ABSTRACT: Efficient blue, green and red phosphorescent OLEDs have been harvested from silver nanoparticles embedded at a glass:Ga-Zr-codoped TiO₂ interface. The embedded silver nanoparticles at the interface removed the non productive hole current and enhanced the efficiencies. The blue emitting device (456 nm) with emissive layer Ir(fni)₃ exhibits a maximum luminance (L) of 40 512 cd m^-2 (ITO - 37 623 cd m^-2), current efficiency (η _c) of 41.3 cd A^-1 (ITO - 40.5 cd A^-1) and power efficiency (η _p) of 43.1 lm w^-1 (ITO - 39.8 lm w^-1) and external quantum efficiency (η _ex) of 19.4% (ITO - 6.9%).
