Abstract
- Pure, Pb 2+ and Bi 3+ doped Li 4 SrCa(SiO 4 ) 2 materials were prepared by using a conventional solid state reaction. The phase of Li 4 SrCa(SiO 4 ) 2 was determined using the powder XRD. The photoluminescent properties of Pb 2+ and Bi 3+ doped Li 4 SrCa(SiO 4 ) 2 materials were investigated using a spectrofluorometer at room temperature. The emission bands of Li 4 SrCa(SiO 4 ) 2 : Pb 2+ and Li 4 SrCa(SiO 4 ) 2 : Bi 3+ were observed at 290 and 380 nm, respectively. Li 4 SrCa(SiO 4 ) 2 with different Pb 2+ and Bi 3+ doping concentrations were analyzed at room temperature. The Stokes shifts of Li 4 SrCa(SiO 4 ) 2 : Pb 2+ and Li 4 SrCa(SiO 4 ) 2 : Bi 3+ were calculated to be 5678 and 5942 cm −1 , respectively. [ABSTRACT FROM AUTHOR]
