✦ Synopsis

Two kinds of bi-functional nanomaterials, CdTe@FeOOH and CdTe@Ni(OH) 2 , were synthesized in water phase. In the synthesis, using the luminescent CdTe nanocrystals (NCs) as a core, Fe 3+ (Ni 2+ ) was added to CdTe NCs aqueous solution and slowly hydrolyzed to deposit a layer of hydroxide onto the luminescent CdTe NCs in the presence of stabilizer. TEM, XRD, XPS, UV, fluorescence spectrometer and physical property measurement system (PPMS) were used to characterize the final products, and the results showed that the as-prepared nanoparticles with core/shell structure exhibited certain magnetic properties and fluorescence.

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 Cu 2 ΓΎ on the preparation of these samples were measured using UV-visible absorption and photoluminescence analysis.

## Abstract We have investigated the evolution of thiol‐capped cadmium telluride nanocrystals prepared in aqueous solutions at low and room temperature followed by heating at 50–100 °C. The UV–visible absorption spectra, as well as transmission electron microscopy, atomic force microscopy, and dyna
