Vanillic acid (VA) is a phenolic acid, and acts as a natural antioxidant in fruits, vegetables and plants. The extraction and determination of trace levels of VA in plants is important, because stimulation of protein synthesis and activation of antioxidant enzymes occur in the presence of phenolic acids at trace levels. In this research, a photoluminescence spectroscopic method was developed for the...
d‐penicillamine‐capped cadmium telluride quantum dots (DPA‐capped CdTe QDs) were synthesized as the new fluorescent semiconductor nanocrystal in aqueous solution. Fourier transmission infrared spectroscopy, X‐ray diffraction, transmission electron microscopy, ultraviolet‐visible and photoluminescence spectroscopy were used for characterization of the QDs. Based on the quenching effect of Cu2+ ions...
