Abstract
- The ratio between the network modifier Li<subscript>2</subscript>O and the network former B<subscript>2</subscript>O<subscript>3</subscript> has a significant influence on the structural and optical properties of Dy<superscript>3+</superscript>-doped lithium borate glass. Differential scanning calorimetry shows that upon increasing the modifier-to-former ratio (Li<subscript>2</subscript>O-to-B<subscript>2</subscript>O<subscript>3</subscript>) in favour of Li<subscript>2</subscript>O, the glass transition temperature increases up to a maximum value of 502°C for the 1:3 sample, while the crystallization temperature decreases linearly from 653 to 534°C. Raman spectroscopy confirms the highest network connectivity for the glass with a modifier-to-former ratio of 1:3. Under ultraviolet excitation, Dy<superscript>3+</superscript> shows emission lines in the visible spectral range, the most intense ones at 484 and 575 nm. The absolute photoluminescence quantum efficiency is best for the glass with a modifier-to-former ratio of 1:6. [ABSTRACT FROM AUTHOR]
