“…[32][33][34][35] Considering the position of the UVvis onsets estimated as the step median, 357 and 341 nm in Figures 1 and 2, the band-gap becomes equal to E g ) 3.5 eV and E g ) 3.6 eV for TG-and AMTP-stabilized NPs, respectively, which indicates the strong quantum confinement of the excitonic transition expected for In 2 S 3 NPs. 36 The position of the adsorption bands correlates well with the UV-vis characteristics of In 2 S 3 specimens prepared by other groups using polymers or in physically constrained media. [37][38][39][40] Indium sulfide NPs stabilized with TG or AMPT can be easily separated from the synthetic liquor by sedimentation with 2-propanol and then redispersed in many polar solvents.…”

“…Because the In-5d states are filled completely with electrons that belong to the closed-shell, they exhibit obvious localized state features (deep energy levels and sharp DOS peaks under the valence band, À14~À12 eV, which is not shown here) in the electronic structure of b-In 2 S 3 . [10,[26][27][28]38] Another important feature can be found in Figure 3. Thus, we did not show them in Figure 2 and Figure 3.…”

“…These results can be compared to previous studies on In 2 S 3 . 26,31,32 The In 2 S 3 XPS VB shows the same structures than the presently studied NaIn 5 S 8 , and the band structure calculations lead to the same assignments for both compounds.…”

“…This band behaves as an outer core state and does not participate in the bonding. [30][31][32] The position of the In 4d 5/2 is 18.5Ϯ 0.1 eV for all compounds. Likewise in order to compare the valence-band shapes, all of the spectra were normalized relatively to In 4d core level.…”
