Sub-single exciton optical gain threshold in colloidal semiconductor quantum wells with gradient alloy shelling
Colloidal quantum wells are highly promising for applications of solution-processed lasers, but their performance is limited by multi-excitonic nature of the materials. Here, the authors demonstrate optical gain in graded alloy core/shell CdSe/CdS@CdZnS quantum wells at less than one exciton per par...
