Figure 3.

Absorption and PL spectra of CdSe/ZnS quantum dots. The quantum dots were embedded in track membranes before and after formation of (a) QD/PAN and (b) QD/PAR complexes. 1 and 2 are the absorbance and PL of the QD embedded in the track membrane, respectively. 3 and 4 are the absorbance and PL of those samples after their impregnation with azo dye solution, respectively.
