1. Overshoot effect in transient electroluminescence from single layer organic light-emitting diodes

Abstract

The overshoot effect in transient electro luminescence (EL) is attributed to an accumulation and trapping of holes at the polymer/metal interface and this effect is enhanced at large reverse bias. The roughness of the Al(sub 2)O(sub 3) has an important bearing on the electron-hole recombination near the interface and its useful manifestation is the appearance of a large EL-spike upon reversing the driving voltage.

3. Dual electroluminescence of an amino substituted 1,3,5-triphenylbenzene

Author

Abstract

Blue-violet electroluminescence was seen in a study of the electroluminescent properties of pEFTP in a vapor deposited layer. EL spectrum exhibits two maxima, one of which is associated with that of photoluminescence. An EL overshoot following switching off a voltage pulse, confirms the significance of detrapping and interfacial phenomena in pEFTP radiative recombination.
