Abstract

The effects of the host crystal structure of an SrTa₄O₁₁: Er³⁺/Yb³⁺ up-conversion (UC) phosphor on its luminescence properties were investigated using the tetragonal tungsten bronze (TTB) and hexagonal polymorphs of the SrTa₄O₁₁ host. Hexagonal SrTa₄O₁₁:Er³⁺/Yb³⁺ showed bright luminescence, whereas the UC emission intensity of TTB SrTa₄O₁₁:Er³⁺/Yb³+ was very weak, corresponding to μ1% that of the hexagonal phase. This result was attributed to the local crystal structure around the rare-earth ions in the host lattice.
