“…In comparison to singly doped phosphors that give only the characteristic emissions of host and doping ions, the doubly doped material synthesized here with two conjugate rare earth ions give tunable emissions over a broad spectral region from 400-700 nm. This interesting characteristic of color tunability is key advantage of synthesized phosphors [61,62].…”

This paper reports structural investigations of rare earth doped BaZrO phosphors synthesized by Solid state reaction technique with varying concentrations of Eu and Tb from 0 mol% to 2 mol%. The synthesized phosphors show enhanced variable emissions in the visible region corresponding to different hypersensitive electronic transitions of Eu and Tb ions. With cubic structure confirmed in XRD analysis, the FESEM images show uniform grain connectivity and homogeneity of prepared samples. The TEM micrographs of the synthesized phosphors show agglomerated irregular structures. The synthesized phosphors were also subjected to FTIR, Raman, EDXS analysis along with studies of thermoluminescent and photoluminescent characteristics. On subjecting to 229 nm (UV) excitation, the phosphors show enhanced PL emissions corresponding to 571 nm (D-F), 591 nm (D-F), 615 nm (D-F) and 678 nm (D-F) hypersensitive transitions of Eu ions and emission peaks at 489 nm (D-F), 539 nm (D-F), 589 nm (D-F) and 632 nm (D-F) accounting for electronic transitions of Tb ions respectively. The computed average PL lifetime is 14.014 s. In the TL analysis, the second order of kinetics with the activation energy varying from 5.0 × 10 eV to 6.6 × 10 eV is reported. The maximum TL lifetime is estimated as 19.4985 min in the TL lifetime analysis.
