Optical and structural characterization of samarium and europium-doped phosphate glasses
Abstract
The work deals with optical and structural properties of aluminophosphate glasses from Li2O–BaO–Al2O3– La the elemental composition of these materials. The in of these glasses has been investigated in relation with their structural characteristics. The optical behavior of these materials has been studied by ultra-violet speci Infrared (FTIR) absorption spectra evidenced as P modes, P2O3–P2O5 system containing Sm3+ and Eu3+ ions. X-ray fluorescence (XRF) has been used to establishfluence of Sm3+ and Eu3+ ions on the optical properties–visible (UV–Vis) spectroscopy, revealing absorption maximafic to the doping ions. Structural information via vibration modes was provided by Fourier Transform symmetrical and asymmetrical stretching vibration bend, PO2 − mode and P peaks speci Sm electron microscopy/energy dispersive spectrometry (SEM/EDS). Fluorescence spectroscopy measurements put in evidence important matrix and 611 nm and 700 nm in the case of Eusymmetrical and asymmetrical stretching vibration modes, P_O stretching vibration water absorbance. Raman spectra acquired by 514.5 nm laser excitation disclosedfic to metaphosphate network. Information about the elemental compositional homogeneity of3+ and Eu3+-containing glasses as well as about the defects of the doped-glasses is revealed by scanningfluorescence peaks found at 596 nm and 643 nm for Sm3+ ions in phosphate3+-doped glass.
