Magic Size Nanoclusters and Methods of Preparing Same

Disclosed herein are magic size nanoclusters comprising lead and one or more chalcogens. The disclosed magic size nanoclusters have both spectrally narrow fluorescence and ultra-high quantum efficiencies. Further disclosed herein is a method for preparing PbS, PbSe, and PbTe magic size nanoclusters. The yield of magic size nanoclusters can be increased by using anion sources enriched for secondary phosphines. The use of enriched secondary phosphine anion sources also increases the yield of quantum nanostructures.
