In this paper, we discussed the optical and luminescence properties of dysprosium oxide containing lithium borate glasses along with the structural properties. Absorption spectra of these glasses show strong absorption bands in ultraviolet and visible regions. Increase in dysprosium oxide content decreases in optical energy band gap, which is explained on the basis of glass structure. These glasses show bright blue emission at 482nm and yellow emission at 573.5nm due to (F9/2H15/2)-F-4-H-6 and (F9/2H13/2)-F-4-H-6 transitions of dysprosium ions.
