Combustion Synthesis and Luminescent Properties of Eu³⁺ and Dy³⁺ Co-Doped Amorphous SrAl₂O₄

Abstract:

Trivalent Eu and Dy ions co-doped amorphous strontium aluminate oxide (SrAl2O4:Eu3+Dy3+) were synthesized through solution combustion route. The phase of the synthesized compound was examined with the X-ray diffractometry. The photoluminescence spectra of the amorphous SrAl2O4:Eu3+Dy3+ has shown that the sharp blue emission of Dy3+ at 483 nm, the sharp yellow emission of Dy3+ at 570 nm and the sharp red emission of Eu3+ at 615 nm can be integrated into the broad blue background emission of the amorphous host. The results indicate that the amorphous SrAl2O4 host can provide good environment to tune the emission color for the SrAl2O4:Eu3+Dy3+.
