摘要

For the first time, we have successfully synthesized rare-earth doped Gd-2(MoO4)(3): RE3+ (RE = Eu, Tb) nanoplates by solvothermal method. The morphology of Gd-2(MoO4)(3) can be manipulated by changing the reaction times and reaction temperatures. The composition and surface morphology have been investigated by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM), respectively. Under the excitation of UV, Photoluminescence (PL) has been used to explore the excellent luminescence properties of the synthesized nanophosphors. The Gd-2(MoO4)(3): Eu3+ phosphors shows a hypersensitive red emission (612 nm) when excitation wavelength within the scope of 200-350 nm corresponding to a D-5(0)-F-7(2) transition. Similarly, the Gd-2(MoO4)(3): Tb3+ phosphors certificate a highly strong green emission at 544 nm at an excitation wavelength of 298 nm corresponding to a D-5(4)-F-7(5) transition. Furthermore, the characteristic spectrum peak of the Gd-2(MoO4)(3): Eu3+/Tb3+ nanophosphor exhibits the corresponding spectra position (green emission at 544 nm and red emission at 612 nm). Hence, the obtained Gd-2(MoO4)(3): RE3+ nanoplates may establish highly potentiality in light field applications.
