Abstract

The development of Flexible Optoelectronic Organic Sensor for Infrared Detection (FOOS-IR), using an optically transparent substrate material and organic semiconductor materials, has been widely utilized by the electronic industry when producing new technological products. The greatest interest in studying organic semiconductor materials has been connected to its already known potential applications, such as: batteries, organic solar cells, flexible organic solar cells, organic light emitting diodes, organic sensors and others. Infrared is a type of electromagnetic radiation that has a frequency lower than that of red light and, therefore, is not within the visible electromagnetic spectrum. For this reason, this radiation cannot be perceived by the human eye. Infrared radiation originates from molecular vibration, which generates oscillations in the electrical charges that make up atoms and causes the emission of radiation, so this type of radiation is associated with heat. In this work, we developed a flexible organic optoelectronic sensor capable of detecting and determining the rate of radiation dose emitted by different sources of infrared radiation. The sensors were developed using optically transparent substrate with Nanostructured thin film layers of Poly(9-Vinylcarbazole) covered by a layer of Poly(P-Phenylene Vinylene) with nanostructured fullerene (C60) and Polyaniline-X1. The samples were characterized by UV-Vis Spectroscopy, Electrical Measurements and Scanning Electron Microscopy. With the results obtained from this study can be developed infrared sensitive OLEDs for applications in night vision systems and infrared technologies in security.
