Abstract

The fabrication and the characterization results of a triple-layer organic light emitting diode (OLED) using a fluorinated Eu3+-β-diketone complex particularly sensitive to UV radiation are presented. The electroluminescence spectra of the devices, fabricated by thermo evaporation carried out in a high vacuum environment, present narrow emission bands characteristics of the Eu3+ ion. The intensity of these peaks decrease as a function of the UV radiation impinging on the device, and is strongly dependent from the UV radiation cumulative dose. The results show that measuring the main Eu3+ emission intensity it is possible to fabricate a portable UV personal dosimeter using this kind of complexes as emitting layer in an OLED device. The OLED emission will be inversely proportional to the UV irradiation exposure.
