Spectra of the diffuse reflectance coefficient (●) and Kubelka–Munk function (○) calculated for the DRS data of SbSI nanowires. Solid curve represents the least square fitted theoretical dependence for the sum of indirect forbidden absorption without excitons and phonon statistics, Urbach ruled absorption, and constant absorption term (description in the text, values of the fitted parameters are given in Table II).
Comparison of the values of energy gap of SbSI nanowires determined using different techniques of diffusive reflection spectroscopy.
Comparison of the values of indirect forbidden energy gap , the Urbach energy and the other parameters of SbSI nanowires with the data of powdered SbSI single crystals (Ref. 3) that were determined from the fitting of the spectrum of Kubelka–Munk function.
