英文摘要 | Comprehensive structural and luminescence study of Sm-doped SiO2-Na2SO4 composite materials have been conducted. The samples were synthesized by melt-mixing mixture of Na2SO4 and SmF3 into the SiO2 matrix at 1050 degrees C for 30 min. XRD pattern shows that the addition of 20% Na2SO4:Sm has no effect on the basic crystal structure of the SiO2. Scanning electron micrograph shows distinct difference in morphological structure between the composite and host SiO2. From photoexcitation (PE) spectra of the as-synthesized composite, the highest excitation efficiency was observed at 402 nm. The photoluminescence (PL) spectra of as-synthesized composite phosphors obtained under 402 nm excitation consist of five narrow emission bands with peaks at 563, 598, 644, 704 and 784 nm, respectively. These are assigned to the (4)G(5/2)-> H-6(j) (J=5/2, 7/2, 9/2, 11/2 and 13/2, respectively) transitions within 4f5 electronic configuration of Sm3+. The highest luminescence intensity was observed from SiO2-10%Na2SO4:Sm. (c) 2013 Elsevier B.V.
