Abstract
In the present work, the glass composition 20Na2O -10PbO-10MO -60B2O3 doped with Praseodymium ions have been synthesised using muffle furnace by the conventional melt quenching technique and the effect of Pr3+ ions on optical properties of present glasses have been examined. The emission spectra were recorded in the wavelength range of 450-750nm upon excitation at 450 and 550nm. The Commission International deI’Eclairage (CIE) chromaticity coordinates are determined to estimate the emission colour of the Pr3+ incorporated barium/calcium/strontium sodium lead borate glasses. It is observed that blue LED and red LED applications can be expected by tuning the excitation wavelength applied to the same glass matrices.
