a Photographs of spots of a QD-mixture on an Au/TLC plate after development with 820-nm light irradiation (intensity: 0.78 W cm−2). The QD mixture contained ZAIS-rod and ACITe-rod QDs with a particle number ratio of 80:20 (Fig. S16). The density of Au NPs immobilized on the TLC plate was 8.7 × 1011 particles/cm2. b Diffuse reflectance spectra (left) and PL spectra (middle) of the spots at Rf = 0.27 and 0.46 on the developed Au/TLC plate. TEM images of QDs extracted from corresponding positions are also shown (right).
