Raman spectroscopy is the inelastic scattering of light by matter. Being highly sensitive to
the physical and chemical properties of materials, as well as to environmental effects that …

Raman spectroscopy has been not only a technique for characterizing the composition and
lattice structure of materials, but also a platform to explore the electron-photon and electron …

In this paper, the dependence of the differential Raman cross section β of the D, G, D′, and
G′ bands of nanographites on the excitation laser energy and also on the crystallite size is …

The role of exciton–phonon coupling in light emission in cesium lead bromide (CsPbBr3)
nanosheets is investigated with combined photoluminescence spectroscopy and the …

In the present work, the nonresonance and resonance Raman scattering by Bi2S3 quantum
dots, with an average size of 2.3 nm and standard deviation of 0.4 nm, is studied. The …

We propose a technique of Raman spectroscopy to characterize the excitonic nature and to
evaluate the relative contribution of the two kinds of electron/exciton–phonon interactions …

Monolayer transition-metal dichalcogenides (TMDs) are emergent semiconductor materials
with a wide range of potential applications. Rydberg excitons are similar to the Rydberg …

Quantum coherence is the key to new quantum technologies, although the details of
decoherence processes and times are still not well understood in solids. We demonstrate …

When excited by circularly polarized light, the Raman scattered light may have the same or
opposite helicity as the incident light determined by the helicity selection rule. For two …

Raman spectra obtained by the inelastic scattering of light by crystalline solids contain
contributions from first-order vibrational processes (eg the emission or absorption of one …
