A Simple Reducing Approach Using Amine To Give Dual Functional EuSe Nanocrystals and Morphological Tuning

Amine for improvement: A non‐injection approach using an amine as a reducing agent is developed to produce spherical EuSe nanocrystals (NCs) exhibiting blue emission (peaking at 403 nm with 2.8 % quantum yield) and room‐temperature magnetic coercivity of 80.2 Oe (see scheme). The NC morphologies can...

Description
Summary:Amine for improvement: A non‐injection approach using an amine as a reducing agent is developed to produce spherical EuSe nanocrystals (NCs) exhibiting blue emission (peaking at 403 nm with 2.8 % quantum yield) and room‐temperature magnetic coercivity of 80.2 Oe (see scheme). The NC morphologies can be controlled easily to be hollow, spherical, or rodlike.
