摘要：

In the present work, the synthesis of BiPO4 phase resided in transparent bismuth phosphate glass ceramics has been accomplished by regular melt quenching route. Impact of modifier fluorides on structural and spectroscopic properties of Dy3+ doped and Eu3+/Dy3+ co doped different bismuth phosphate glass ceramics via PXRD, FTIR, XPS, SEM, optical absorption, emission, excitation and decay measurements has been thoroughly examined. Various spectroscopic parameters were calculated from the absorption spectra using Judd-Ofelt (J-O) theory and analyzed the parameters. From the emission spectra, emission characteristics were studied via optical band gains (sigma(e) x tau(R)), gain bandwidths (sigma(e) x delta lambda(eff)), Y/B ratios and lifetimes (tau) from decay curves. The effect of Eu3+/Dy3+ co-doping on emission properties has been studied in these glass ceramics where energy transfer was observed. Color coordinates for all the studied systems also inferred. Among various multi component glass ceramics studied in the present work, NaF2 system could be suitable for laser and white light applications.
