Preparation and characterization of rare earth Sm-doped borophosphate luminescent material

ABSTRACT

CaBPO₅: Sm³⁺ was synthesized by using high-temperature solid-state method. The structures and luminescence properties of products were studied by X-ray diffraction (XRD), photoluminescence (PL), scanning electron microscopy, and Fourier transform infrared spectroscopy. The XRD test indicated that CaBPO₅ single phase was gained after 6 h sintering under 1000°C. The PL test presented that CaBPO₅: Sm³⁺ had three main emission peaks at 563, 599, and 654 nm under 401 nm UV excitation. The emission peak at 599 nm had a higher peak intensity than the other two peaks. The effect of Sm³⁺ concentration on luminescence properties was analyzed. With an increase in Sm³⁺ concentration, the luminous intensity of samples first increased, then decreased, and finally reached the peak at 0.75 mol% of Sm³⁺ concentration.
