| 초록 | A series of Dy 3+ or/and Eu 3+ doped Y 2 Mo 4 O 15 phosphors were successfully synthesized at a low temperature of 600 o C via solid state reaction. The as-prepared phosphors were characterized by X-ray powder diffraction (XRD), scanning electronic microscope (SEM), photoluminescence (PL) excitation, emission spectra and PL decay curves. XRD results demonstrate that Y 2 Mo 4 O 15 : Dy 3+ , Eu 3+ has the monoclinic structure with the space group of p21/C(14). Under the excitation of ultraviolet (UV) or near-UV light, the Dy 3+ and Eu 3+ ions activated Y 2 Mo 4 O 15 phosphors exhibit their characteristic emissions in the blue, yellow and red regions. The emitting light color of the Y 2 Mo 4 O 15 : 0.08Dy 3+ , yEu 3+ phosphors can be adjusted by varying the concentration ratio of Dy 3+ to Eu 3+ ions and a white light is achieved when the doping concentration of Eu 3+ is 5%. In addition, the energy transfer from Dy 3+ to Eu 3+ is also confirmed based on the luminescence spectra and decay curves. |
