Photoluminescence of Eu3+-doped La2Mo2O9 phosphors

Eu(3+)-doped La(2)Mo(2)O(9) phosphor was fabricated by sold-state reaction method. The as-prepared samples were characterized by the application of X-ray diffraction (XRD), scanning electron microscopy (SEM), and emission spectra. The effect of the sintering temperature and doping amount of europium ion on the luminescent properties of La(2)Mo(2)O(9):Eu(3+) was investigated. The results show that the luminescent intensity will reach the strongest when the sintering temperature is equal to 1073 K. The Eu(3+) doping amounts also have obvious effect on the luminescent properties.
