The influence of Ce~(3+) doping concentration on luminescence of Y_(3)Al_(5)O_(12):Ce~(3+) phosphors synthesized by combustion method

摘要

Powder phosphors of yttrium aluminum garnet Y_(3)Al_(5)O_(12)(YAG), activated with trivalent cerium (Ce~(3+)) was synthesized by combustion from mixed metal nitrate reactants and urea with ignition temperature of 500C deg approx 550C deg. Sintering the precursor can improve the crystallization of YAG: Ce~(3+) phosphors so to promote the luminescence intensity. The influence of the concentration of Ce~(3+) on the luminescence character was studied. The crystalline structure and morphology are observed by X-ray powder diffraction picture and SEM picture respectively.
