Mg3N2 powders of high quality were synthesized by a simple nitridation reaction of Mg powder with ammonia (flow rate 500 mL/min) at the nitridation temperature of 800 ℃ for 60 min. X-ray diffraction (XRD) result indicates that Mg3N2 possesses body centered cubic in structure with the lattice constant being a= 0.996 57 nm. SEM analysis indicates that Mg3N2 powders have different morphologies. Photoluminescence spectrum under excitation at 490 nm shows that these Mg3N2 powders have a green emission peak at 545 nm (2.3 eV)
