Abstract

We report the absorption spectra (at 10 K) for SbI₃ clusters with molecular numbers 1/2, 1 and 2 which were created in FAU-zeolite cages. At 2.0 - 3.7 eV there appear bands whose energies strongly depends of the loading densities of SbI₃ molecules. These energies are remarkable blue shifted compared with the one of the bulk exciton (2.615 eV). This shift is interpreted in terms of the quantum size effect. The observed blue-shift of absorption bands coincides with one calculated in m_h/m_e>>1 approximation (typical for MI₃ layered crystals).
