photoluminescence of the dark-exciton replica in monolayer WSe2. Gate and magnetic-field dependent PL measurements unveil a circularly-polarized replica peak located below the dark exciton by 21.6 meV, equal to E″ phonon energy from Se vibrations. First-principles calculations show that the ...

The maximum of the bandgap is about 2 eV in monolayer BP and near 0.3 eV in thick BP. In Fig. 2C, the thickness dependent band gap is obtained based on experiments, i.e. the photoluminescence [52] and electrical transport property [53]. The band gap measured based on the transport ...
The bandgaps of trilayer, bilayer, and monolayer MoS2, determined by photoluminescence, change from 1.35 to 1.65 and 1.8 eV [154], respectively. The bandgap of other typical TMDCs, such as WSe2, MoSe2 [146], WS2 [147], and GaTe [148], also increases with decreasing layer thickness, ...
Nanopatterning of defects in TMDCs have introduced additional functionality in 2D materials, leading to new optical and electronic devices. Chalcogen vacancies can induce sub-bandgap emission peaks and increase the overall photoluminescence intensity in TMDCs.83Optical properties of other intentionally doped...
The generation of ⋅OH radicals may be studied in detail through photoluminescence (PL) spectroscopy using terephthalic acid (TA) as probe molecules. The TA molecules without fluorescent can further react with ⋅OH radicals to generate 2-hydroxyterephthalic acid (HTA) molecules with strong ...
