Summary:In this research, we used the solid-state reaction method to synthesize the Eu 2 O 3 -doped Sr 3 Al 2 O 6 powder with the different temperatures. The Eu 2 O 3 -doped Sr 3 Al 2 O 6 powder was synthesized at 1000°C-1300°C for 4 h. The variations in the morphologies of Eu 2 O 3 -doped Sr 3 Al 2 O 6 phosphors were observed using a FESEM. As the synthesizing temperature increases, the crystallization and particle sizes of the Eu 2 O 3 -doped Sr 3 Al 2 O 6 composition are significantly improved. From the photoluminescence excitation spectrum we found that 240 nm was the optimum excitation optical wavelength to excite the Eu 2 O 3 -doped Sr 3 Al 2 O 6 phosphors. We had also found that the emission (PL) spectra of the Eu 2 O 3 -doped Sr 3 Al 2 O 6 phosphors had sharp peaks in three strong peaks at 389, 592, and 612 nm and had small peak in two weak bands at 290 nm and 651~653 nm.
