We synthesized the phosphors of (Ba1−xEux)0.79(Al1−yZny)10.9O17.14−δ (0.05 ≤ x ≤ 0.15, 0 ≤ y ≤ 0.25) by a solid-state reaction. To obtain a single phase of the phosphor, various processing conditions were investigated: particle sizes, sintering times, and optimal composition of Ba. Thus, we succeeded in synthesizing the single phase, and the brightest emission was observed at x = 0.1 for Eu. Moreover, the color changed from green to blue with the addition of the Zn2+ ion in the Al3+ site, and with an increase in the Zn content, the photoluminescence intensity increased. The color change was closely related to the crystal structure of the phosphor.
