Abstract
Oxide inorganic electroluminescent device in which thin films of Pr-doped NaNbO3 phosphor and Sb-doped SnO2 transparent conductor are alternately stacked was prepared by sol-gel and spin-coating methods. Red electroluminescence was observed due to f-f transitions of Pr3+ ions by applying 5-kHz ac voltages to the device. The luminance was 1.0 cd m−2 at 25 V ac and5.0 cd m−2 at 34 V ac.
