Abstract

LuVO

:Eu

nano-(or submicron-) phosphors have been prepared by hydrothermal method without (or with) further heat treatment. The properties of the resulting phosphors are characterized by X-ray diffraction

scanning electron microscope

photoluminescence spectra and decay curve. The excitation spectra of LuVO

:Eu

phosphors are mainly attributed to EuO charge-transfer band at about 275 nm as well as some sharp lines of Eu

f-f transitions in near-UV and visible regions with two strong peaks at 395 and 466 nm

respectively. Under the 275 nm excitation

intense red emission peak at 619 nm corresponding to

transition of Eu

is observed for LuVO

:8%Eu

phosphors as the optimal doping mole fraction. The luminescence properties suggest that LuVO

:Eu

phosphor may be applied as a potential red phosphor candidate for lighting and displays.
