Utilisation des nanoparticules pour l’amélioration des performances des sources organiques (OLED) AYENEW Getachew
Simulation (PWE) • To have plot of (radius/period) vs refractive index contrast • Experiment • OLEDs and Nanoparticlesfor light extraction
Bandgap Δn Radius/period
Simulation • Radius scan for low refractive index material (TiO2,n=2.5)
Experiment: Objective: OLED + Nanoparticles-light extraction • Nanoparticledepostion on ITO coatedsubstrate • substrat cleaning (solvents +UV ozone) • dipcoating • Refrencesubstrates • substrat cleaning (solvents +UV ozone)
OLED Deposition ( with Mahmoud) • ITO/CUPC/TPD/Alq3/Al • Characterizaion
