摘要

The optical and electrical properties of the new [In_16]_Oh[In_5.33-xNa_3x□_2.66-2x]_TdS_32 (BINS) thin films have been studied. The determination of the optical band gap of films containing different rates of sodium has shown that it linearly increases from 2.10 eV, when the films are pure β-In_2S_3, to 2.95 eV, when their sodium content corresponds to x=0.9 i.e. [In_16]_Oh[In_4.4Na_2.7□_0.9]_TdS_32 compound. This evolution of the band gap has been discussed in terms of In-S bond length and electronegativity of an and In elements.
