Abstract

Broadband electroluminescence emission from fullerene crystals is reported and described. The spectral distribution is comparable to that of the photoluminescence at high excitation densities. The emission intensity is nonlinearly dependent on the current. The response of the crystal to the application of an alternating current is investigated and the frequency dependence of the emission intensity is described. The observed high frequency cut-off behaviour cannot be mimicked by a simple equivalent circuit and so the system is modelled using a rate equation model to describe the state of the system. Fits of the model to the observed behaviour provide rate constants which compare favourably to those reported for excited state decay in fullerenes.
