Electroluminescence in CaO:Eu Thin Film

概要

• 論文の詳細を見る

• A CaO:Eu thin film electroluminescent (EL) cell was fabricated and its EL characteristics were studied. A sharp emission at 595 nm, a weak emission around 620 nm and a broad-band emission around 720 nm were observed. The emissions at 595 nm and 620 nm were assigned to the ^5D_0→^7F_1 and ^5D_0→^7F_2 transitions in Eu^<3+> ions, respectively. The emission around 720 nm could be the 4f^65d→4f^7 transition in Eu^<2+> ions taking into consideration the fact that a smaller anion-cation distance in CaO would decrease the Eu^<2+> emission energy in calcium chalcogenide host lattices.
