Abstract

A study applied Er ions to the large-scale 2D MoS2thin films synthesized by chemical vapor deposition (CVD) technique. Both up-conversion (UC) and down-conversion (DC) photoluminescence (PL) emissions located in NIR spectral regime were first observed in 2D layered transition metal dichalcogenides (TMDs) simply using a single wavelength near-infrared (NIR) pumping source. Luminescence wavelengths of the rare-earth (RE)-doped 2D TMDs were greatly extended and tuned compared to pristine counterpart.
