Preparation and photoluminescence properties of euxenite-type YNbTiO6 and YNbTiO6:xRE3+, yMn2+ (REÂ =Â Er, Dy) micro/nanophosphors

- YNbTiO6-based phosphors were synthesized by a sol-gel combustion method.
- The annealing temperature plays the key role of PL properties and particle size.
- Luminescence of Mn2+, Er3+, and Dy3+-doped YNbTiO6 host was achieved.
- Luminescent mechanism of Er3+ or Dy3+-doped samples is dipole-dipole interaction.
- Mn2+ → Er3+ (Dy3+) energy transfers were observed for co-doped phosphors.
