| dc.description.abstract | The aim of this work is to investigate the effect of CaxSr2-x and activator on the structural and luminescent properties of green-emitting CaxSr2-xSiO4:Eu2+ nano phosphor. Using urea as fuel and ammonium nitrate as oxidizer, CaxSr2-xSiO4:Eu2+ has been successfully synthesized, using a combustion method. The particles were found to be small, spherical and of round surface. SEM imagery showed that the phosphors particles are of nanosize. The CaxSr2-xSiO4:Eu2+ emission spectrum for 360 nm excitation showed a single band, with a peak at 490 nm, which is a green emission. The highest luminous intensity was at 1,000℃, which was obtained when the Eu2+ content (y) was 0.05. The results support the application of CaxSr2-xSiO4:Eu2+ phosphor as a fluorescent material for ultraviolet light-emitting diodes (UV-LEDs). Characteristics of the synthesized CaxSr2-xSiO4:Eu2+ phosphor were investigated by means of X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and photoluminescence (PL) detection. ©2014 KIEEME.
