Thermal Enhancement of Upconversion Luminescence in Negative-Thermal-Expansion Ho3+-Doped Yb2−xW3O12 Phosphors

The fluorescence intensity of lanthanide (Ln 3+ )-doped upconversion (UC) materials generally exhibits significant thermal quenching with increasing temperature, which is a critical challenge for their application. In this work, Yb 2−x W 3 O 12 :xHo phosphors with thermally enhanced UC luminescence...
