摘要：

The Eu3+-doped NaY(MoO4)(2) phosphors with a scheelite structure were synthesized using the microwave assisted hydrothermal process without further sintering treatment. X-ray powder diffraction (XRD) analysis indicates that the as-prepared products keep the tetragonal structure of NaY(MoO4)(2). Scanning electron microscopy (SEM) images show that with prolonging the reaction time the morphologies of NaY0.9(MoO4)(2):0.1Eu(3+) phosphors evolve from rice-like to cubic micro-structure. The photoluminescence (PL) spectra demonstrate that the phosphors emit strong red light centered at 615 nm corresponding to D-5(0) -> F-7(2) transition of Eu3+ ion under 465 nm excitation, which is in good agreement with the emission wavelength from blue light-emitting diodes (LEDs).
