Abstract
In this study, Lead doped Barium-Strontium silicate (BaSrSiO4:Pb2+) phosphor was synthesized using a combustion method. The photoluminescence characteristics of the BaSrSiO4:Pb2+ phosphor particles were improved by the co-doping system. The characteristics of the synthesized (BaSr)2SiO4:Pb2+ phosphor were investigated using X-ray diffraction (XRD), a Scanning Electron Microscope (SEM), and photoluminescence (PL). The BaSrSiO4 XRD patterns became shaper and stronger at the concentration of Bax=0.05 with a (103) main peak. The maximum emission band of the BaSrSiO4:Pb2+ was observed to be 423 nm.
Keywords: (BaSr)2SiO4, phosphor, combustion method, light-emitting diode
