Figure 5
(a) UV–vis absorbance spectra of the CdSe NPs in the presence of 5 wt% DDA. (b) PL spectra of the CdSe NPs for the same solution. The spectra were normalized with respect to the PL intensity at 8.1 s. (c) Stability of products (CdSe NPs) (3 s) recorded as intensity variations of specific spectral features in the UV–vis spectra (d) as a function of elapsed time. The time scale of fluctuation is much shorter than the integration time (4 s) which averages out the variation.
