What the Last Cut Costs

Linewidth against yield in six antisolvent cuts of one InP/ZnS batch

A research poster from the School of Settled Matters splits one batch of InP/ZnS quantum dots into two arms and fractionates each by six successive antisolvent cuts, one cutting at first turbidity and one by fixed volume. In the turbidity arm the second to fourth cuts hold 60% of the batch at a pooled linewidth of 39 nm against the parent's 46 nm, while the fifth and sixth recover 23% no narrower than the parent and at the lowest quantum yields, so the poster recommends stopping after the fourth cut.
