Effect of Dy2O3 impurities on the physical, optical and thermoluminescence properties of lithium borate glass

Dysprosium (Dy) doped lithium borate glass (LBG) is prepared using conventional melting-quenching technique with varying Dy concentration in the range of 0 to 1.0 mol%. Prepared glass samples are characterized via X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), UV-vis-IR, Photoluminescen...
