Abstract Synthesis of semiconductor nanoparticles with new photophysical properties is an area special interest. Here, we report synthesis ZnS in aqueous micellar solution Cetyltrimethylammonium bromide (CTAB). The size nanodispersions has been calculated using UV-vis spectroscopy, XRD, SAXS, and TEM measurements. are found to be polydispersed the range 6–15 nm. Surface passivation by surfactant molecules studied FTIR fluorescence spectroscopy. have better stabilized CTAB concentration above...
Colloidal nanodispersions of ZnS have been prepared using aqueous micellar solution two cationic surfactants trimethylammonium/pyridinium series with different head groups i.e., cetyltrimethylammonium chloride (CTAC) and cetyltrimethylpyridinium (CPyC). The role these in controlling size, agglomeration behavior photophysical properties nanoparticles has discussed. UV-visible spectroscopy carried out for determination optical band gap size nanoparticles. Transmission electron microscopy...
The well defined emission properties of CQDs have encouraged further investigation their prospects in chemo-sensing applications for the identification Cr<sup>3+</sup> ions aqueous media.
The presence of heavy metal ions in the environment and food items can severely harm human health. Thus, simple, reliable, sensitive, quick, accurate methods for their detection must be developed as a means to improve healthcare worldwide. To this end, robust method was direct sensing arsenic(iii) control real environmental samples (at neutral pH) by gold electrode that modified with zirconia nanocubes synthesized via facile hydrothermal route. This system used build profile arsenic after...
