1 LABORATOIRE DE PHYSIQUE DES LASERS Photonique Organique Utilisation des nanoparticules pour l’amélioration des performances des sources organiques (OLED) AYENEW Getachew

2 ►Simulation (PWE) ► To have plot of (radius/period) vs refractive index contrast ► Experiment ► OLEDs and Nanoparticles  for light extraction 2

3 3 Radius/period ΔnΔn Bandgap

4 Simulation ►Radius scan for low refractive index material (TiO2,n=2.5) 4

5 Experiment: Objective: OLED + Nanoparticles-light extraction  Nanoparticle depostion on ITO coated substrate o substrat cleaning (solvents +UV ozone) o dip coating  Refrence substrates o substrat cleaning (solvents +UV ozone) 5

6 ►OLED Deposition ( with Mahmoud) o ITO/CUPC/TPD/Alq3/Al o Characterizaion 6
