Optimization of Synthetic Parameters for Efficient NIR Luminescence in Ytterbium-doped CsPbCl3 Perovskite Quantum Dots

Abstract

Ytterbium-doped perovskite quantum dots show promise for optoelectronic and imaging applications, yet achieving efficient Yb incorporation remains challenging. We systematically optimized synthesis parameters including reaction temperature, precursor stoichiometry, OA/OAm ratio, and ligand content, which indeed strongly govern Yb incorporation efficiency and emission intensity.
