Photo- and Radioluminescence Properties of Eu3+-doped Y2O3 Thick Film Phosphor Prepared via Chemical Vapor Deposition

Abstract

We demonstrate the high-speed epitaxial growth of a Eu 3+ -doped Y 2 O 3 (Eu 3+ :Y 2 O 3 ) thick film phosphor grown on a (100) yttria-stabilized zirconia substrate by laser-assisted metalorganic CVD. The deposition rate was 42 m h -1 and the resultant 7-m-thick Eu 3+ :Y 2 O 3 film was optically transparent. Under UV and X-ray irradiation, the Eu 3+ :Y 2 O 3 thick film emitted red light originating from the 5 D 0 7 F 2 transition of Eu 3+ ions with a fluorescence decay time of 1.7 ms.
