Abstract CdS and alloyed CdSxSe1−x nanocrystals were luau thank you cards prepared by a simple noninjection method without nucleation initiators.Oleic acid (OA) was used to stabilize the growth of the CdS nanocrystals.The size of the CdS nanocrystals can be tuned by changing the OA/Cd molar ratios.On the basis of the successful synthesis of CdS nanocrystals, alloyed CdSxSe1−x nanocrystals can also be prepared by simply replacing certain amount of S precursor with equal amount of Se precursor, verified by TEM, XRD, EDX as well as UV–Vis absorption analysis.The optical properties of the alloyed CdSxSe1−x nanocrystals can be tuned by adjusting the S/Se feed molar ratios.

This synthetic approach developed is highly reproducible and can be readily scaled up for color touch 7/97 potential industrial production.
