Provided are a method of preparing a zinc silicate-based phosphor and a zinc silicate-based phosphor prepared using the method. The method includes: (a) preparing a solution including a Zn precursor compound and a Si precursor compound; (b) adding a coprecipitant to the solution to form precipitation; and (c) heat treating the solution in which the precipitation is formed to synthesize zinc silicate (ZnSiO), wherein a solvent of the solution including the Zn precursor compound and the Si precursor compound includes at least one selected from the group consisting of ethanol, methanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, 1-pentanol, 2-pentanol, 3-pentanol, 1-hexanol, and 1-heptanol, and hydrazine is used as the coprecipitant.
