The near-infrared luminescent material is capable of efficiently emitting near-infrared light with a peak wavelength of 900 nm to 1,100 nm under an effective excitation wavelength of 250 nm to 750 nm. The luminescent material has the characteristics of wide excitation emission wavelength, high luminous efficiency, uniform luminescence, no impurity phase, high stability, simple preparation and the like. The present invention further provides the light-emitting device prepared from the near-infrared luminescent material. The luminescent material and the light-emitting device provided by the present invention solve the problems of poor stability, low luminous efficiency, high preparation cost and the like of a conventional near-infrared luminescent material and light-emitting device, and have a favorable application prospect.
