5. Conclusion
In summary, it is concluded that we have developed highly transparent and brightly colored Mn2+, Co2+
and Ni2+ ions doped ZnO–PbO–B2O3 (ZPB) glasses for evaluating their optical potential as luminescent materials based on their absorption, excitation, emission spectral results. All the features given in various figures and the results tabulated in different tables of the present work are considered to be more useful results towards the progress of transition metal ions doped optical glasses. Due to the availability of Zn and Pb ions in the ZPB glasses, they have been found to possess good resistance towards the humidity conditions in the laboratory even up to several months together. XRD profiles have confirmed their glassy nature more clearly and the FTIR profiles have been used to understand the bonding nature of these glasses. The analysis made through various optical tools strongly suggest that these glasses have potential applications as luminescent optical materials.
