Up-conversion behaviors of nano-structure BaTi0.9Sn0.1O3 activated by Er3+/Yb3+ ions

Fabrication of TiO2 based Dye-Sensitized Solar Cell using Nerium oleander as a sensitizer

“…On comparison with bare TiO2, the 1 mol% Er-doped TiO2 has less peak intensity and high dislocation density that confirms the incorporation of Er 3+ ion into TiO 2 lattice. From table 1, it is noticed that after the addition of 1 mol% of Er, there is decrease in volume of unit cell and crystallite size but there is increase in dislocation density that may be due to the variation in the ionic radii of Ti 4+ (0.605 Å) and Er 3+ (0.89 Å) [19,20].…”
