Photograph of different-sized CdTe QDs and the corresponding absorption and photoluminescence spectra. Photograph of different-sized CdTe QDs (stabilized by both HPAMAM and MPA) made under an UV lamp (top) and the corresponding absorption (bottom) and photoluminescence (PL) spectra (bottom). The PL emission peaks were at 509, 546, 563, 578, 605, and 629 nm, respectively.
