Abstract:
An orange-emitting phosphor, Eu(2+)-activated LiSr4(BO3)3, was synthesized using the conventional solid-state reaction. The photoluminescence excitation and emission spectra, and temperature dependence of the luminescence intensity of the phosphor were investigated. The results showed that LiSr4(BO3)3:Eu(2+) could be efficiently excited by incident light of 250-450 nm, and emits a strong orange light. With increasing temperature, the emission bands of LiSr4(BO3)3:Eu(2+) show an abnormal blue-shift with broadening bandwidth and decreasing emission intensity.
