N2 - Lamp phosphors including [Ca10 (PO4)6 (Cl,F):Sb:Mn], (Y,Eu) 2O3, BaMgAl10O17:Eu, and (La,Ce)PO4:Ce:Tb, with or without flux, have been synthesized by a microwave processing technique in a multimode microwave furnace operating at 2.45 GHz. The microwave-synthesized phosphors were comprehensively characterized for particle size, specific surface area, brightness, and luminescence. Although most properties of the microwave-synthesized phosphors were comparable to that of the conventional products, the kinetics of the phosphor synthesis was substantially enhanced in the microwave process. As a result, the soaking time at the peak temperature was reduced by up to 90% compared to a conventional process. In addition, the required synthesis temperature was also lowered by 100-200°C in microwave process, compared to the conventional process for these lamp phosphors. The advantages of microwave process for the lamp phosphor synthesis are obvious.
