The present invention relates to a green light-emitting diode. The green light-emitting diode according to the present invention comprises: an LED element which generates a wavelength in the ultraviolet region; and a phosphor which converts the light generated from the LED element to a green wavelength, and the phosphor is made as strontium barium orthosilicate, and is indicated by the chemical formula given below. The green light-emitting diode which is provided in this way has a high efficiency; with a light-emitting efficiency which is at least 1.6 times and at most 3 times that achieved hitherto. [Chemical formula] Baw + Srx + Euy + Cez·Si04 (0.88=w=0.22, 0.68=x=1.05, 0.06=y=0.08, 0.01=z=0.02) |
