By Rebecca MartineauNREL Communications Professional Just one year after NREL materials science researchers Matthew Hautzinger and Sage Bauers met to exchange notes on underexplored materials in nanotechnology, their synthesis of promising Zintl-phase quantum dots is attracting attention with its bright photoluminescent glow, chemical stability, and Earth-abundant ingredients. “Recently, scientists have reassessed material compounds that were developed 40–50 years ago but largely forgotten...
