%X The near–infrared luminescence properties of Ni2+ doped the near–stoichiometric LiNbO3 (SLN) single crystals have been investigated. Under a laser diode excitation source at 980nm, a near–infrared luminescence in Ni2+:SLN single crystals centers at 1087 nm with its FWHM about 72 nm was found. The fluorescence decay properties of crystal were measured, and the fluorescence lifetime of Ni2+:SLN single crystals was as long as 240 μs even at room temperature. The observed near–infrared fluorescence can be attributed to the 3T2g(3F) →3 A2g(3F) transition of Ni2+ in octahedral sites.
