Zn-3(BO3)(2) nanoparticles; doping Ce3+ and Al3+ ions; luminescence properties
Zn-3(BO3)(2) nanoparticles doped with Ce3+ and Al3+ have been prepared by co-precipitation method. The study on the XRD pattern and Fourier transform infrared spectroscopy (FT-IR) shows that the diffraction lines are in good agreement with monoclinic crystalline phase of Zn-3(BO3)(2). Ce3+ -doped Zn-3(BO3)(2) nanoparticles show a broader emission band at 405 nm, which is attributed to the d-f transition 5d-4f(1) of Ce3+. The effect of Al3+ on luminescence properties of Ce3+ has been studied. The results show that the fluorescence intensity of Ce3+ is enhanced greatly. (C) 2004 Elsevier B.V. All rights reserved.
