Abstract

ZnS nanoparticles were obtained by chemical precipitation from a solution (CPD) on porous silicon (PS) prepared by chemical etching of an n-type silicon wafer (100) with a solution of fluoride acid (HF) at room temperature. A thorough study was carried out using structural methods such as atomic force and scanning electron microscopy (AFM, SEM). The optical properties of the fabricated ZnS-PS materials were investigated and it was shown that the synthesis of nanoscaleZnS particles in silicon pores revealed new photoluminescence (PL) characteristics, such as bright and stable radiation in the visible part of the spectrum, even at room temperature.
