Abstract

Polycrystalline powders of AgLa1−xEux(PO3)4 (with x = 0.01, 0.05, 0.10 and 0.20) were synthesized using the flux method. These powders were systematically characterized by scanning electron microscopy, energy dispersive X-ray detector, X-Ray diffraction, fourier transform infrared spectroscopy, and photoluminescence spectroscopy. All diffractograms show similarity and correspond to the monoclinic structure of lanthanum phosphate. Spectroscopic properties of the Eu3+ doped AgLa(PO3)4 at room temperature are also investigated and showed significant improvement in the red emission intensity and decay time for 5D07F1 transition (590 nm), which embodies the fluorescent decay characteristic of microsized phosphors, indicating potential applications in opto-electronic devices.
