Sintering temperature effect on structural and luminescence properties of 10 mol% Y substituted Gd3Al5O12:Ce phosphors
چکیده انگلیسی

Y (10 mol%) substituted GAG:Ce (GdYAG:Ce) phosphors have been synthesized by solvothermal reaction method and which were sintered at various temperatures. The XRD patterns confirm that the GdYAG:Ce phosphors have garnet structures with a single cubic phase. GdYAG:Ce phosphors were stable with pure garnet phase at higher temperatures and lower concentration of Y3+ ions. The SEM images of these phosphors show spherical morphology. The luminescent properties of these phosphors have been investigated by the measurement of their emission and excitation spectra. The excitation spectra of GdYAG:Ce phosphors consist of a broad band with a maximum at 485 nm and also the emission spectra of these phosphors emit the reddish yellow colors with a peak intensity at 546 nm from the measured spectra.
