Cadmium CdTe nanorod

Nanomaterials in the form of a colloidal solution or quantum dots are attributed to have a tremendous impact in analytical chemistry for their unique physical and chemical properties (Alivisatos 2004 Katz and Willner 2004). A different methodology has been adopted to analyse vitamin Bi spectro-fluorimetrically by using cadmium selenide quantum dots (CdSe QDs), cadmium telluride (CdTe) nanorods, and silica and gold nanoparticles. A fluorescence resonance Rayleigh scattering (RRS) method was applied for determining vitamin Bi at sub-nanomolar level (Liu et al. 2006). In this technique, vitamin Bi was mixed with acidic buffer and prepared gold nanoparticles. After incubation, the solution mixture was excited in synchronous mode to obtain RRS spectra. The RRS spectral intensity correlated with the concentration of vitamin Bi. [Pg.249]

Recently, our group has reported the synthesis of CdTe nanorods using solvothermal route from two different single source molecular precursors and their subsequent characterization by XRD and SEM [271], Initially, the single source molecular precursor Cadmium complex of bis-(aminopropyl) telluride has been prepared as per the scheme shown below (Fig. 6) ... [Pg.205]

Surface modification can also promote different photoluminescence responses to chemical species present in the environment. Li et al.48 synthesized water-soluble luminescent thiol-capped CdTe QDs and nanorods and investigated the effect of divalent metal ions on their photoluminescence behavior. They found that the trends of photoluminescence changes were almost similar for both, CdTe QDs and nanorods. Moreover, zinc ions enhanced the luminescence emission of the QDs while other metal ions (e.g., calcium, magnesium, manganese, nickel, and cadmium) caused luminescence quenching. [Pg.384]
