Abstract
Enhancement in electroluminescent performances have been harvested with embedded silver nanoparticles at glass and Ga-Ti-codoped ZnO interface. The blue emitting device exhibit maximum luminance (L) of 40268 cd/m2 (ITO device II-38863 cd/m2), current efficiency (ηc) of 38.3 cd/A (ITO device II-36.0 cd/A) and power efficiency (ηp) of 41.6 lm w−1 (ITO device II-40.3 lm w−1) with external quantum efficiency (ηex) of 19.2% (ITO device II-17.0%). Newly fabricated green device with emissive layer Ir(fpi)3 show intensified emission at 520 nm and luminance of 44894 cd/m2 (ITO device-IV-41682 cd/m2), current efficiency (ηc) of 40.6 cd/A (ITO device IV-39.4 cd/A), power efficiency (ηp) of 43.4 lm w−1 (ITO device IV-39.4 lm w−1) and external quantum efficiency (ηex) of 15.6% (ITO device IV-14.1%).
