By designing highly soluble precursors , Cd 3 P 2 /ZnS quantum dots (QDs) can be prepared at room temperature. They are shown to be air‐stable, size‐tunable, and of high optical quality (quantum yields over 50 %). A large photoluminescence range can be covered by simple modulation of the concentration of reactants (see picture) and of the temperature (30 °C, 90 °C).
