The synthetic application of prenucleation‐stage samples of colloidal semiconductor quantum dots (QDs) is in its infancy. It is shown that when two prenucleation‐stage samples of binary CdSe and CdS are mixed, ternary CdSeS magic‐size clusters (MSCs) grow at room temperature in dispersion. As the amount of the CdS sample increases, the optical absorption of the CdSeS MSCs blueshifts from ≈380 to ≈360...
