Rare-earth doped phosphors with negative thermal expansion (NTE) may display thermally-enhanced emission, but their performance is generally limited. Here the authors report thermally-boosted green upconversion luminescence and near-infrared downshifting luminescence in Sc2(MoO4)3:Yb/Er phosphors with two-dimensional NTE, and their application in temperature sensing.
