Hot-carrier trapping preserves high quantum yields but limits optical gain in InP-based quantum dots
Bright emitters without gain
We study InP/ZnSe/ZnS QDs10 with a photoluminescence quantum yield of 95% for 420-nm excitation (Fig. 1a, high-resolution TEM image). Figure 1b shows the absorbance spectrum (black line) with the band-edge absorption…

Gated CO2 permeation across dynamic graphene pores
Carbon capture from flue gas emission requires the separation of CO2 from N2 and O2. CO2/O2 separation is more challenging than CO2/N2. O2 permeates faster than N2 because of its smaller kinetic diameter (3.30, 3.46, and 3.64 Å for CO2, O2,…
