Abstract
A light-emitting diode () has a first electrode (), a second electrode (), a light-emitting layer () which comprises a matrix, and ions. A layer () of a cation receptor (CR) is positioned adjacent to the first electrode (), has captured cations, and has generated immobilized cations (+). A layer () of an anion receptor (AR) is positioned adjacent to the second electrode (), has captured anions, and has generated immobilized anions (−). The ion gradients provide for quick response in emission of light (L) when the diode () is exposed to a forward bias. A diode () is manufactured by first forming a laminate () of the above structure. The laminate () is exposed to a forward bias to make the ions become immobilized at respective sites (S, S) of the respective receptors (CR, AR).
