07/06/2016В В· Biomedical applications require nanocrystals with a narrow emission spectra and low toxicity. One major challenge of using quantum dots (QDs) in biomedical studies has been to synthesize them in large quantities while retaining desirable optical properties. To date, no research has been carried out to scale up the synthesis of InP/ZnSe mized thickness, high-quality InP/ZnS core-shell QDs were synthesized with a narrow size distribution and high emis-sion quantum yield (QY) comparable to CdSe QDs.14 In this letter, we present our investigation of the optical nonlinearity on these QDs, and it is shown that the colloidal InP/ZnS QDs exhibit strong SA in near resonant regime and
