Abstract: PURPOSE: A method for preparing zinc silicate-based phosphors is provided to synthesize a nano phosphor with uniform particle size distribution, and to enable a low-temperature process. CONSTITUTION: A method for preparing zinc silicate-based phosphors comprises the steps of: preparing the solution including Zn and Si precursors; forming a precipitate by adding a co-precipitator in the solution; and heat-treating the solution and synthesizing zinc silicate. A zinc silicate-based phosphor uses at least one selected from the group consisting of ethanol, methanol, 1-propanol, isopropanol, 1-butanol, 2-butanol, 1-pentanol, 2-pentanol, 3-pentanol, and 1-hexanol and 1-heptanol and uses hydrazine as a co-precipitator.
