Streamer electroluminescence (EL) is observed in anthracene single crystals. Impulse voltage is applied to anthracene crystals 1_??_4mm in thickness at the pressure range of 1.3_??_4.0×104Pa (100_??_300 Tort). When the applied voltage reaches a threshold voltage, normal EL suddenly changes to streamer EL. Next, when the applied voltage is lowered, the streamer EL returns to normal EL below the threshold voltage. Furthermore, the intensity of streamer EL is about ten times higher than that of normal EL. The peak wavelength of the streamer EL spectrum is the same as that of normal EL.
