• the charge transfer capabilities have been discussed as follows. Figure 4 shows photographs of the polymer P3HT and the polymer nanocomposites of P3HT:CISe, P3HT:CIGSe and P3HT:CZTSe nanocrystals in toluene exposed to a UV lamp. A clear color gradation from left to right is visible. The first one

• quenching and charge transfer capabilities of each of the synthesized nanocrystals CISe, CIGSe and CZTSe when forming polymer nanocomposites with P3HT. Figure 5a–c shows the emission intensity (λmax = 580 nm) profiles of nanocomposites of CISe:P3HT, CIGSe:P3HT and CZTSe:P3HT dispersed in toluene. As evident

• in Figure 5a, a more pronounced decrease of the emission intensity of the P3HT:CZTSe composite is observed with an increasing CZTSe concentration compared to P3HT:CISe and P3HT:CIGSe polymer nanocomposites. This corroborates the suggestion that a more efficient electron transfer is taking place

• . For an aspect ratio of 3, NRs polymer nanocomposites with a maximum transmission of 93% in the region between 700–800 nm have been fabricated. CTA nanocomposites The 9–15 µm thin CTA nanocomposite layers containing NRs (aspect ratio 6) on glass exhibit bright orange luminescence (see Figure 9). The
