      Se presenta una revisión del estado actual de dispositivos orgánicos emisores de luz (OLED, acrónimo de organic light-emitting diode), con énfasis en aquellos que emiten en la franja del rojo. Para entender el funcionamiento de este tipo de dispositivos, se muestran las diferentes arquitecturas utilizadas y los mecanismos de emisión de estos dispositivos optoelectrónicos por radiación fluorescente y fosforescente. Para el caso de emisores color rojo, se presentan ejemplos con dos tipos de materiales mayormente usados: DJCTB para fluorescencia e Ir(piq)2(acac) para fosforescencia. Si bien las arquitecturas y mecanismos aquí revisados se aplican a emisores rojos, también pueden ser extendidos a emisores en todo el rango visible.

      A review of the current state of organic light-emitting devices (OLED) is presented, with an emphasis on those that emit in the red band. To understand the operation of this type of device, the different architectures used and the emission mechanisms of these optoelectronic devices by fluorescent and phosphorescent radiation are shown. For the case of red emitters, examples with the two most commonly used types of materials are presented: DJCTB for fluorescence and Ir(piq)2(acac) for phosphorescence. Although the architectures and mechanisms herein reviewed apply to red emitters, they can also be extended to emitters throughout the visible range.
