UV-vis absorption and PL spectra of CdTe QDs. UV-vis absorption and PL spectra (a-d) of in situ prepared CdTe QDs obtained by adding different amounts of HPAMAM and heating at various times. The inset in (c) shows fluorescent photographs of as-prepared CdTe QDs under UV irradiation. Photoluminescence spectra were recorded with excitation at 370 nm.
