We demonstrate the high-speed epitaxial growth of a Eu3+-doped Y2O3 (Eu3+:Y2O3) thick film phosphor grown on a (100) yttria-stabilized zirconia substrate by laser-assisted metal–organic CVD. The deposition rate was 42 μm h−1 and the resultant 7-μm-thick Eu3+:Y2O3 film was optically transparent. Under UV and X-ray irradiation, the Eu3+:Y2O3 thick film emitted red light originating from the 5D0→7F2 t ransition of Eu3+ ions with a fluorescence decay time of 1.7 ms.Corresponding author: Akihiko Ito
