A series of Ce 3+ doped CaLu 2 Al 4 SiO 12 garnet phosphors was prepared by a sol–gel combustion technique. All samples were characterized by powder X-ray diffraction (XRD), thermal quenching (TQ), fluorescence lifetime and photoluminescence (PL) measurements. Moreover, luminous efficacies (LE), CIE 1931 color points and quantum efficiencies (QE) were determined and...
Y 3−x Lu x Al 3 MgSiO 12 :Ce 3+ phosphors were prepared by aqueous sol–gel technique. Samples with 0.25, 0.5, 0.75 and 1mol-% of Ce 3+ were fabricated and characterized by powder X-ray diffraction (XRD), photoluminescence (PL) spectroscopy, and temperature dependent luminescence to reveal the thermal quenching. Moreover, luminous efficacies (LE),...
