| description | In this study, a series of Li<sub>2</sub>O-Al<sub>2</sub>O<sub>3</sub>-B<sub>2</sub>O<sub>3</sub> glasses doped with various concentrations of Dy<sub>2</sub>O<sub>3</sub> (where x = 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0 mol%) were prepared by using a conventional melt-quenching technique. The structural, physical and optical properties of the glasses were examined by utilising a variety of techniques instance, X-ray diffraction (XRD), UV–Vis-NIR spectrometer, Fourier transform infrared (FTIR) and photoluminescence (PL). The XRD spectra demonstrate the amorphous phase of all glasses. Furthermore, the UV-vis-NIR spectrometers have registered optical absorption spectra a numbers of peaks which exist at 1703, 1271, 1095, 902, 841, 802, 669, 458, 393 and 352 nm congruous to the transitions from the ground of state (<sup>6</sup>H<sub>15/2</sub>) to different excited states, <sup>6</sup>H<sub>11/2</sub>, <sup>6</sup>F<sub>11/2</sub> + <sup>6</sup>H<sub>9/2</sub>, <sup>6</sup>F<sub>9/2</sub> + <sup>6</sup>H<sub>7/2</sub>, <sup>6</sup>F<sub>7/2</sub>, <sup>6</sup>F<sub>5/2</sub>, <sup>6</sup>F<sub>3/2</sub>, <sup>4</sup>F<sub>9/2</sub>, <sup>4</sup>I<sub>15/2</sub>, <sup>4</sup>F<sub>7/2</sub> and <sup>6</sup>P<sub>7/2</sub>, respectively. The spectra of emission exhibit two strong emanation bands at 481 nm and 575 nm in the visible region, which correspond to the transitions <sup>4</sup>F<sub>9/2</sub> → <sup>6</sup>H<sub>15/2</sub> and <sup>4</sup>F<sub>9/2</sub> → <sup>6</sup>H<sub>13/2</sub>. All prepared glass samples doped with Dy<sub>2</sub>O<sub>3</sub> show an increase in the emission intensity with an increase in the concentration of Dy<sup>3+</sup>. Based on the obtained results, the aforementioned glass samples may have possible applications, such as optical sensor and laser applications. |
