Electroluminescence of a Multilayer in which Thin Films of NaNbO sub(3):Pr Phosphor and SnO sub(2):Sb Transparent Conductor Are Alternately Stacked

Electroluminescence of a Multilayer in which Thin Films of NaNbO sub(3):Pr Phosphor and SnO sub(2):Sb Transparent Conductor Are Alternately Stacked

Oxide inorganic electroluminescent device in which thin films of Pr-doped NaNbO sub(3) phosphor and Sb-doped SnO sub(2) transparent conductor are alternately stacked was prepared by sol-gel and spin-coating methods. Red electroluminescence was observed due to f-f transitions of Pr super(3+) ions by...

Zusammenfassung:Oxide inorganic electroluminescent device in which thin films of Pr-doped NaNbO sub(3) phosphor and Sb-doped SnO sub(2) transparent conductor are alternately stacked was prepared by sol-gel and spin-coating methods. Red electroluminescence was observed due to f-f transitions of Pr super(3+) ions by applying 5-kHz ac voltages to the device. The luminance was 1.0 cd m super(-2) at 25 V ac and5.0 cd m super(-2) at 34 V ac.
