چکیده انگلیسی
CdS microstructures with uniform rose-flower-like morphology were successfully synthesized on a large scale through the physical vapor deposition method. The morphology, crystal structure and optical properties of the final product were characterized using SEM, XRD, TEM, SAED, Raman spectroscopy and photoluminescence spectroscopy. The flower-like CdS microstructures are assembled by many interleaving nanosheets which have a uniform thickness of about 40 nm and a high-crystalline structure with dominant surfaces as {21¯1¯0} planes. The room temperature photoluminescence spectrum of the rose-like microflowers reveals a strong green emission at 513 nm corresponding to band edge emission. On the basis of SEM and TEM observations, a comprehensive mechanism for the formation and growth of CdS microflowers is proposed.
