Abstract

The paper presents investigation results on surface modification influence of monocrystalline zinc sulfide substrates on their optical transmission and photoluminescence spectra. One of characteristic peculiarities of the samples considered is the presence of wide 2.5- 3.2 eV structureless irradiation band at CdS fundamental absorption region. Apart from this, absolute transmission decreases and transmission edge shifts into low-energy region of ~0.1 eV upon surface modification. Observed peculiarities of CdS optical properties can be explained by quantum-scale effects in nanocrystalline modified surface layer, experimentally detectable with atomic force microscopy.
