Absorption, PL, and fluorescence emission spectra. (a) Absorption and PL spectra (λex = 365 nm) of CdTe QDs with different reflux times; (b) fluorescence emission spectra of CdTe QDs under UV (365 nm) irradiation. The maximum emission wavelengths of the CdTe QDs in (a) were 525 nm (15 min), 544 nm (30 min), 559 nm (60 min), 579 nm (90 min), 588 nm (120 min), 599 nm (150 min), 625 nm (210 min), and 641 nm (270 min), respectively.
