Abstract
A thin-film electroluminescent (EL) device with a ZnS:Mn emitting layer grown by a metalorganic chemical vapor deposition method using carbon disulfide as a sulfur source has been prepared on a BaTiO3 ceramic sheet used as an insulating layer. The luminance of 1 nt under the applied voltage (sinusoidal wave of 5 kHz) of 7 V is attained for the EL devices with a ZnS:Mn emitting layer 170 nm thick, and 20 V with a 400 nm thick layer. The maximum luminance and luminous efficiency obtained are 6300 nt and about 11 lm/W, respectively. A device driven with an applied voltage of 100 V at 60 Hz exhibits a luminance of 200 nt.Keywords
