1：Experimental Design and Method Selection:

The study involved the synthesis of In(OA)3 precursors under different conditions to control the amount of residual acetate ions. The effect of these ions on the optical properties and size distribution of InP/ZnSeS QDs was then examined.

2：Sample Selection and Data Sources:

InP core QDs were synthesized using In(OA)3 precursors with varying amounts of acetate ions. The optical properties and size distributions of these QDs were analyzed.

3：List of Experimental Equipment and Materials:

Materials included In(Ac)3, Zn(Ac)2, ODE, Se powder, S powder, TOP, (TMS)3P, and oleic acid. Equipment included a UV–Vis spectrophotometer, spectrofluorometer, TEM microscope, and XRD diffractometer.

4：Experimental Procedures and Operational Workflow:

In(OA)3 precursors were prepared by reacting In(Ac)3 with oleic acid under varying conditions. InP core QDs were then synthesized and coated with a ZnSeS shell. The optical properties and size distributions of the resulting QDs were analyzed.

5：Data Analysis Methods:

UV–Vis absorption and PL spectra were recorded, and PL QYs were measured. TEM and XRD analyses were conducted to examine the size distribution and crystal structure of the QDs.
