- Provided are a blue phosphor for a fluorescent display having a high luminous efficiency, and a method for synthesizing the same. The blue phosphor is obtained from a host composed of strontium carbonate (SrCO3) and an activator composed of a cerium compound. The method for synthesizing the blue phosphor includes preparing a mixture having strontium carbonate (SrCO3) and a cerium oxide (CeO2) homogenously mixed according to the composition having the following general formula:SrCO3+xCeO2wherein 0.01≦x≦0.5, and annealing the mixture at 800 to 900° C.
