Blue Electroluminescence of Thin-Film Diamond Made by the Hot-Filament Method

Yasushi Taniguchi; Keiji Hirabayashi; Keiko Ikoma; Noriko Kurihara; Masaaki Matsushima

Blue electroluminescence has been observed in thin-film diamond deposited on a substrate when a mixture of methane and hydrogen gases react under heat treatment by tungsten filament. The diamond active layer is sandwiched between metal oxide insulating layers (HfO2 and Al2O3) which are formed by evaporation of metal oxides in oxygen plasma. Indium tin oxide film is used as a transparent electrode. The electroluminescence spectrum shows the peak at 435 nm and luminance is 3.6 cd/m2 at an applied voltage of 400 V.
