The invention discloses a light-emitting low-temperature co-fired LED (light-emitting diode) ceramic powder which is formed by calcining the following components: 60-80 parts of nano calcium oxide, 80-100 parts of aluminum oxide, 50-65 parts of aluminum hydroxide, 30-45 parts of magnesium hydroxide, 20-25 parts of calcium nitrate tetrahydrate, 12-15 parts of tetraethoxysilane, 10-18 parts of methyltriethoxysilane, 8-10 parts of sodium silicate, 5-6 parts of excitant, 4-8 parts of dysprosium oxide, 3-5 parts of silver halide and 3-5 parts of silver chloride. The light-emitting low-temperature co-fired LED ceramic powder has the advantages of low sintering temperature, controllable dielectric constant, low dielectric loss, high mechanical strength and certain luminescent intensity.
