Abstract

© 2018, S.C. Virtual Company of Phisics S.R.L. All rights reserved. At this work, it is presented a new route to produce ammonia-free cadmium sulfide tetrapod nanoparticles at room temperature using three precursors, cadmium nitrate, polyethyleneimine and thioacetamide by chemical bath deposition method. The tetrapod cadmium sulfide nanoparticles were characterized by UV-Vis spectrum, transmission electronic microscope and Raman analysis. The optical band gap of tetrapod nanoparticles was 2.78 eV, the length of the arms was 39.45 nm and its width was 3.27 nm. From TEM was found an orthorhombic crystallographic structure of the nanoparticles and vibration modes (1LO = 272.79 nm and 1LO = 292.79 nm).
