2 What is an OLED? OLED is the acronym for Organic Light Emitting Diode An OLED is a solid-state device composed of thin films of organic molecules that create light with the application of electricity Doesn t require any backlight Self emitting Light weight and thin (100 to 500 nanometers thick) Flexible Low power consumption High contrast, brighter and wide viewing angle (170 ) 2
3 OLED Basic Scheme Multilayer device Voltage - + Cathode ETL Electron Transport Layer /Electroluminescent Layer HTL Hole Transport Layer Anode Substrate LIGHT Electrons injection Holes injection Recombination Light emission 3
4 Diagram of OLED emission process In the emitting region, the interaction between holes and electrons doesn t lead directly to the carriers recombination Injection from anode h γ e Injection from cathode η 1 h e pair 1 Singlet exciton 3 Exciton: excited bound pair state Triplet exciton η 3 η 2 Emission Thermal Deactivation Radiationless Deactivation External Emission Φ el = γη 1 η 2 η 3 Internal Emission Φ el = [χ s Φ fl η s + χ t Φ ph η t ]η r η e Maximum internal quantum efficiency for fluorescence emission = 25% Phosphorescent materials (heavy metal complexes, like Ir(ppy)3, PtEOP, etc) can convert triplet states to singlet emitting ones, 4 so internal quantum efficiency can reaches almost 100%
5 Efficiency of OLED Balance of electron and hole currents from injection: 1 can be reached Injection and transport of charges must be efficient for good power efficiency 75% Triplet, 25% Singlet excitons: 25% for fluorescent materials Using phosphorescent materials (Forrest/Thompson) and optimizing recombination zone, almost 100% efficiency can be reached Because of flat structure of the device and mismatching of refractive indexes of layers, up to 80% of generated light can be lost to wave guide modes Light must be efficiently extracted from the device 30 5
6 Light outcoupling OLEDs are devices made of flat layers with different refractive indexes Generated light presents total internal reflection at the interfaces External radiation can be up to 20-30% only of generated light! EQE Light extraction strategies 6
7 OLED encapsulation Organic materials and low work-function metals react very quickly with water and oxygen of atmosphere, degrading devices performances Very good protection needed with sealing, encapsulation and getters to achieve useful lifetime (> h) of OLEDs for applications Rigid For glass based displays Flexible For FOLED displays Utilizes a glass sealed by epoxy resin and a getter to absorb residual humidity Utilizes thin film of flexible and impermeable material to insulate the device

29 ENEA innovative materials for OLED in collaboration with Dept. of Chemistry, University of Naples Natural Pigments Inspire the Design of Biocompatible Materials in Organic Electronics: Melanins The use of such biodegradable materials can be an answer to the problem of electronic waste. For this reason growing attention is paid to the design and development of nature-inspired materials for organic electronics applications. Our idea is to use natural pigments (melanins) in OLED applications. Our main goals of the melanin-inspired research are: 1) the design, synthesis and characterization of new melanin-inspired photoluminescent materials for OLED applications; 2) the development of melanin-based material for ITO replacement. Melanin precursors HO HO HO N H NH 2 Chemical and physical properties Extremely low radiative quantum yield Photo- and electrical conductivity Broad band absorption in the entire UV-Vis spectrum Free radical and redox behavior HO Main goals of the melanin-inspired research line Design, synthesis and characterization of new melanin-inspired photoluminescent materials for OLED applications.
