Abstract. In this work, we use chemical vapor deposition (CVD) technique to synthesize CdS 1D-nanostructures (nanobelts & Sea-Urchin like nanostructures). The morphological characterizations of the product were examined by optical microscope, while optical properties are investigated by Photoluminescence (PL) spectroscopy. PL spectroscopy helps to identify the crystallinity of the nanostructures. Those structures show only bandedge (BE) emission confirm the highest crystalline quality whereas some structures show broad band emission . Harrison Cassidy, Lauren Bower, Ren. ée Carew, . Tosin. .
