CdTe@Cu(OH)(2) nanocomposite: Aqueous synthesis and characterization

Mahmmoud Sayed, Abd El-sadek LU and Babu, S. Moorthy (2011) In Journal of Solid State Chemistry 184(5). p.1135-1140
Abstract
CdTe@Cu(OH)(2) nanocomposites were synthesized in aqueous solution by a seed-mediated growth approach. The effect of refluxing time and the concentration of Cu2+ on the preparation of these samples were measured using UV-visible absorption and photoluminescence analysis. The emission peak of the synthesized nanocomposites (CdTe@Cu(OH)(2)) was shifted from 605 (CdTe seed) to 621 nm. The size of CdTe nanoparticles were averaged about 3.22 nm, and the CdTe@Cu(OH)(2) nanocomposites were averaged as 5.19 nm. The synthesized CdTe@Cu(OH)(2) nanocomposite were characterized with XRD, EDAX, TEM, FT-IR, EPR, and thermal analysis (TG/DTG curves). The results indicate that as-prepared nanoparticles with core/shell structure exhibit interesting optical... (More)
