Abstract The aluminate luminescent material for infrared light detection belongs to the field of luminescence and display technology, and said material includes: (a). compound substrate containing Al and at least one kind of alkali earth metal compound is added; (b). compound activator containing rare earth Sm, Eu, Dy and Ge; and (c). compound containing rare earth or at least one of Mn, Bi, or Ti and flux borate. When infrared excitation light is in 0.8-1.3 micrometer wavelegnth, it can produce luminescent display of 530-440 nm, specially it is applicable to low-power semiconductor laser.
