Photoluminescence Improvements and Decay Time Enhancements in Novel Eu doped AgLa(PO3)4 Luminophores
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 5D0 → 7F1 transition (590 nm), which embodies the fluorescent decay characteristic of microsized phosphors, indicating potential applications in opto-electronic devices.
