dc.description.abstractEn | Self-organized honeycomb (HC) polymer films were fabricated as a bottom-up assembly and deposited onto glass substrates in order to create extraction layers for blue OLEDs. Relying on the fast and tunable " Breath Figure " process, HC films were prepared on a minute timescale and incorporated onto OLED devices, either through direct bottom-up formation onto the OLED substrates or through an original and convenient peeling/transfer method. Two types of HC films differing in period and morphology were prepared, and eventually led to an EQE improvement of 25% measured on an OLED whose emitter molecules are oriented parallel to the plane, using a vapor deposition at room temperature. Additionally, we have modeled the optical characteristics of the HC films, leaning on the fact they are periodic and very regular. This 3D optical model, complemented by a 1D electrical model to determine the Emission Zone Profile (EZP), predicts that the photonic films we fabricated are able to enhance up to 29% the EQE, and opens perspectives for a better design of extraction layers. | |
