Figure 3From: Facile preparation of highly luminescent CdTe quantum dots within hyperbranched poly(amidoamine)s and their application in bio-imagingThe absorption and emission spectra of CdTe aqueous solution. Prepared within 120 mg HPAMAM before and after being aged for 1 year. The CdTe QDs sample was synthesized by heating for 280 min, and its absorption peak was 577 nm.Back to article page
