Linewidth and lifetime

NettetA spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules.These "fingerprints" can be compared to the previously collected ones of … Nettetlifetime in tungsten- and molybdenum-based TMDs: in MoSe 2, the coherence lifetime is determined by radiative coupling at low temperatures and by phonon-induced intravalley scattering at room temperature. In contrast, the excitons in WS 2 can be efficiently scattered into the energetically lower-lying intervalley dark excitonic state, cf. Fig. 1.
