Combustion synthesis and luminescent properties of Eu~(3+) and Dy~(3+) co-doped amorphous SrAI_2O_4

摘要

Trivalent Eu and Dy ions co-doped amorphous strontium aluminate oxide (SrAl_2O_4:Eu~(3+)Dy~(3+)) 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 SrAl_2O_4:Eu~(3+)Dy~(3+) has shown that the sharp blue emission of Dy~(3+) at 483 nm, the sharp yellow emission of Dy~(3+) at 570 nm and the sharp red emission of Eu~(3+)at 615 nm can be integrated into the broad blue background emission of the amorphous host. The results indicate that the amorphous SrA^C^ host can provide good environment to tune the emission color for the SrAl_2O_4:Eu~(3+)Dy~(3+).
