Size-Controlled Synthesis of Tetrametallic Ag@CoNiFe Core-Shell Nanoparticles Supported on Graphene: A Highly Efficient Catalyst for the Hydrolytic Dehydrogenation of Amine Boranes
Dual-mode excitation β-NaGdF4:Yb/Er@β-NaGdF4:Yb/Nd core–shell nanoparticles with NIR-II emission and 5 nm cores were synthesized using an ultra-low single dose of NaF.
