Abstract

A new optical glass with the molar composition 20B₂O₃-50P₂O₅-10Li₂O-9Al₂O₃-5ZnO-3Dy₂O₃-3Tb₂O₃ was obtained by melting-quenching technique comprising wet route raw materials preparation, and the structural and optical characteristics of the glass were investigated by different experimental techniques. The amorphous nature was confirmed by X-ray diffraction (XRD) and the thermal stability was assessed by differential thermal analysis (DTA). Information about the defects of the co-doped glass as well as about the elemental compositional homogeneity was revealed by scanning electron microscopy/energy dispersive spectrometry (SEM/EDS). Structural information provided by Fourier Transform Infrared (FTIR) and Raman spectroscopy indicated metaphosphate structure of the glass together with boron oxide mostly in [BO₃] Q² units and also P[sbnd]O[sbnd]B bonds. Ultraviolet–visible (UV–Vis) absorbance, photoluminescence (PL), photoluminescence excitation (PLE) and time resolved photoluminescence (TRPL) spectra and luminescence decay curve were investigated systematically. Energy transfer process between Dy³⁺ and Tb³⁺ ions and its influence on luminescent properties were discussed.
