  1. Novaled Novaled Development of innovative whiteOLEDs for high qualitylighting in art exhibitions project PON04a3_00369

  2. High qualitylightingapplications Source: PHILIPS

  3. Keyfeatures of high qualitylighting • High CRI (Color Rendering Index) • No emission in UV and IR • Good color • Good light comfort • High efficiency • Beautiful design of the lamp

  4. OLEDs for lighting FINAL GOAL: REPLACEMENT OF STANDARD LIGHT SOURCES FOR IN-DOOR LIGHTING LUMIBLADE by PHILIPS ADVANTAGES: • New architecturepossibilities • Largeareas, ultra-thinthicknesses • High qualitylighting • Goodvisive comfort Early Future by Ingo Maurer/OSRAM

  5. Organicemitters in solution OLED structure The world of OLEDs Cluster Tool machine in Lecce Market trends for OLEDs (Display Search)

  6. Focus on the problems • Low efficienciescomparedtofluorescenttubes • Not easy tofabricate on flexiblesubstrates • High costs Why? ANODE MATERIAL: BRITTLE AND EXPENSIVE

  7. The IDEA: multiple microcavityOLEDs • Anode material substitution with a metal mirror metallicmicrocavity • 1 Microcavity=amplifiedemission in the resonancewavelength=monochromatic light • Multiple microcavities=differentresonancewavelengths=white light

  8. Project objectives Developmentof OLED prototypes with the followingfeatures: • Efficiency of 60 lm/W • 90 CRI • Standard lighting color • Large area (5x5 cm) • Flexiblesubstrates

  9. Whatisalreadydone Currentmulticavity OLED prototypeshave the followingfeatures: • Efficiencyof35 lm/W • 85 CRI • Warmwhite color • Small area • Best efficiency on flexiblesubstrateseverreported: 15lm/W Researchchallenges: • Efficiencyimprovement • CRI improvement • Active area scale up

  10. Collaborations & contacts COLLABORATIONS: • CNR-NANO Lecce, NanotechnologyResearch Center CONTACTS: • Armando Genco: g.rnd@libero.it • Twitter: #evOled_ITA
