High refractive index of Eu3+ doped La2O3-TiO2-Nb2O5-WO3 oxide glasses with low wavelength dispersion

Lithium-aluminum-borate glasses doped with single, double, or triple Tm3+, Tb3+, or Eu3+ ions, respectively, at several concentrations were prepared. Structural characterization was performed using optical absorption and luminescence spectroscopy. The transition for the rare earth ions under study was observed in optical absorption and some for-host glass at wavelengths less than 300 nm. The luminescence of Eu3+, Tb3+, and Tm3+ is presented as bright red, green, and blue emissions, respectively. White light was produced by adjusting the excitation wavelength and doping concentration of Tm2O3, Eu2O3, and Tb4O7. The sample doped with triple rare earth ions produced color emissions from Tb and Tm to Eu, which varied in hue based on the excitation wavelengths of 350, 360, and 370 nm. The glass samples under investigation may be promising for optoelectronic devices and security applications such as data encryption.
