“…For indirect band-gap MoSi 2 N 4 , it is mainly the phonon-assisted electronic transitions that contribute to the absorption of light with energies near the electronic band gap. According to second-order perturbation theory and first-principles calculations, we calculate IPDF due to phonon-assisted electronic transitions by eq 2 ,, where ℏω k ,α and n k ,α are the energy and Bose occupations of the phonon state, respectively, with wave vector k and polarization index α and g n ′ k ′, m k k ′– k ,α is the electron–phonon matrix element. The sum over ± accounts for phonon absorption and emission; η is a small Lorentzian broadening, which is set to 0.1 eV …”

“…NPs of Au, Ag, and Cu can display different optical properties by adjusting their composition, [34] size, [47,48] morphology, [49][50][51] structure and surface features, [52][53][54] and have been developed into the most versatile and flexibly tailored nanomaterials. Especially, these metal NPs present readily tunable colors originating from their unique LSPR effect.…”

“…It is well known that the LSPR of Au could not only broaden the visible light absorption [ 40 ] but generate “hot electrons” participating in the chemical reactions [ 41 ] to improve the photocatalytic efficiency. To demonstrate this effect in our system, a comparison test for 4‐NP degradation with 10% MS/Au/T photocatalyst was performed under UV and simulated solar light.…”
