Description
This paper describes the preparation of Eu-doped strontium aluminate phosphors using a solid-state reaction method and the evaluation of their luminescence properties. The strontium aluminate phosphors co-doped with different rare earth ions were prepared, and photoluminescence (PL) measurements were performed. The results showed that Tb was more suitable than Tm as a photosensitizer for the three rare-earth-element-activated samples. The photoluminescence experiments showed that Eu and Dy, which are co-activated with two rare earth elements, were easily phosphorescence, and Eu, Dy, and Tb, which are co-activated with three rare earth elements, were also phosphorescence at similar temperatures. Considering the above two facts, it was confirmed that the combination of Eu, Dy, and Tb is the best material for luminescence intensity and phosphorescence.
