The invention relates to a blue-green LED (light emitting diode) light-emitting material. A chemical structural formula of the material is M6-x(GayAl1-y)14SiO29:xEu, wherein M refers to at least one or more of group-II alkaline-earth metal elements, x is larger than or equal to 0.001 and smaller than or equal to 1, and y is larger than or equal to 0 and smaller than or equal to 1. An emission waveband of the synthesized target light-emitting material is 490-510nm, the deficiency of spectrum at a blue-green light wave band in existing LED packaging is effectively filled, and the synthesized target light-emitting material is high in luminance and heat stability. In addition, after the synthesized target light-emitting material is matched with other light-emitting materials to obtain LED lamps by packaging, a color rendering index can reach 95 or above.
