Photoluminescence properties of rare earths (Eu3+, Tb3+, Dy3+ and Tm3+) activated NaInW2O8 wolframite host lattice

► Characteristic emissions of rare earths (Eu3+, Tb3+, Dy3+ and Tm3+) are observed NaInW2O8 wolframite. ► Energy transfer from host to the activators (Eu3+ Dy3+ Tm3+ is observed. ► PL properties of rare earth ions depend on minor structural variations in the host lattice.
