Optical Design of a PMMA Sensor Film for Organic Light Emitting Diode

Chaya Bangalore Muniraju, Pavithra Gattu Subramanyam and Sneha Umesha


The organic light emitting diode (OLED) is an optoelectronic system that operates on the principle of electroluminescence, i.e., the recombination of electrons and holes in the organic/active layer. It serves as the primary source of light for the sensing film that is used to sense the sample (bioreceptor) target analyte. The PMMA (Polymethyl methacrylate) sensor film is used to detect analytes (blood and glucose) with a 540 nm working range. The OLED is simulated to overcome glass/substrate losses resulting from total internal reflection and also to achieve maximum the OLED device’s outcoupling efficiency by putting into practice a few of the most useful layers, such as injection layers, blocking layers, and so on, in a systematic way because the sensitivity of the sensing film is dependent on the amount of light emitted from OLED. To reduce substrate losses and improve the effectiveness of light extraction, a layer of magnesium fluoride (MgF2) nanospheres was placed on the substrate.
