dc and pulsed electroluminescence (EL) in tetracene crystals have been studied at room temperature. The crystals are provided with Na/K alloy electron injecting contact and Au semitransparent layer as a hole injecting contact. dc EL intensity shows a superlinear relationship with crystal current. EL decay indicates that the electroluminescence in tetracene consists of two components: one prompt and a second delayed component. The results can be understood if the delayed component depends upon crystal current and upon some characteristics of the active traps in the crystal. The spectral distribution of the electroluminescence as compared to photoluminescence spectrum reveals the intensive long wavelength emission. It is presumably due to trapped excitons.
