Abstract

original image

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.
