Abstract: PURPOSE: Provided is a process for producing spherical green phosphor powder for a plasma display or a lamp by a spray-pyrolysis method optimizing the composition of precursors. CONSTITUTION: The process for producing the spherical green phosphor powder(formula, Zn2-xSiO4:Mnx) comprises the steps of: preparing a precursor solution of the phosphor powder by dissolving a zinc precursor selected from zinc nitrate, zinc acetate, and zinc chloride and a manganese precursor selected from manganese sulfide, manganese chloride, manganese acetate, and manganese nitrate in distilled water and dissolving 105-125%(based on the zinc) of tetraethyl ortho-silicate(TEOS) in distilled water with a very small amount of nitric acid and alcohol or dispersing nano-sized SiO2 powder, produced by a gas or liquid phase method, in the solution, wherein the total concentration of the precursor solution is 0.02-3M; injecting the precursor solution into a sprayer to generate droplets having a diameter of 0.1-100 micrometer; injecting the droplets into a tube type reactor with a high temperature of 200-1500deg.C: additionally, oxidation- or oxidation/reduction-heating the obtained phosphor powder at 800-1350deg.C for 1-5hours. In the formula, 0.011
