Description 775-781
Ba0.5Ca0.5La2-x-y(MoO4)4:xEu3+,yDy3+ with doping concentrations of xEu3+ and yDy3+ (x =0.01, 0.03, 0.05, 0.1 and y=
0.01) phosphors were synthesized by solid state reaction method, one of the high temperature solid state methods. The
reactions were carried out in tube furnace at determined temperatures. Thermogravimetry-differential thermal analysis
(TG/DTA) system was used to determine the synthesis temperature of the material and to examine its thermal behavior. The
crystal structure of the material was checked with x-ray powder diffractometry (XRD), surface morphology and elemental
analysis were done with scanning electron microscope (SEM). The photoluminescent properties of luminescence and
excitation wavelength and luminescence duration were determined by photoluminescence spectrophotometer (PL). As a
result of the analyses made with photoluminescence spectrophotometer, three emission bands were observed at 619 nm, 652
nm and 706 nm, resulting from the characteristic 5D0→7Fj (J=2, 3 and 4) transitions of Eu³+ ions.
