White electroluminescence (EL) was observed for the first time from diamond-like carbon (DLC) films at room temperature. ac voltages in excess of 200 V were applied to a metal-insulator-semiconductor (i.e., DLC)-insulator-metal device structure to observe EL. At an applied voltage of 235 V, the brightness and efficiency were 0.5 fl and 0.002 lm/W, respectively.
