Abstract

In this study, the synthesis and Nanocrystallites properties of one of the main semiconductors has been investigated which has high efficiency in detection, recognition and identification. Thus, PBS Nanocrystallites have been synthesized through wet chemistry using a capping agent (2-mercaptoethanol). Some properties including crystal, optic and morphology structure and the size of PBS Nanoparticles has been investigated through X-Ray diffraction, UV-VIS spectroscopy and STM (Scanning Tunneling Microscopy). The excitonic shoulders of PBS Nanoparticles become visible by clusters' shrinkage through VIS spectroscopy.2-mercaptoethanol capping agent leads to handling of cluster size, and the increase of its concentration leads to much shifts in the shoulders. X-Ray diffraction approved the certain shoulders of PBS and the high purity of Nanoparticles, and the size of particles was calculated by Scherrer equation.Furthermore, based on STM, 4-5 nm Nanoparticles with high dispersion and spherical shape were observed. The innovation in this work is reaching PBS Nanoparticles with ENERGY GAP of around 4.1 eV which has not been reported in other papers so far.
