Enhancing Photoluminescence of CsPb(ClBr) Perovskite Nanocrystals by Fe Doping.

The doping of impurity ions into perovskite lattices has been scrupulously developed as a promising method to stabilize the crystallographic structure and modulate the optoelectronic properties. However, the photoluminescence (PL) of Fe-doped mixed halide perovskite NCs is still relatively unexplored. In this work, the Fe-doped CsPb(ClBr) nanocrystals (NCs) are prepared by a hot injection method.

Slow-Relaxation Behavior of a Mononuclear Co(II) Complex Featuring Long Axial Co-O Bond.

Co(II) mononuclear complex with different coordination geometry would display various of field-induced single-ion magnet (SIM) behaviors. Here, we identify a field-induced single-ion magnet in a mononuclear complex Co(HDPA)·HO (HDPA = 2,6-pyridine-dicarboxylic acid) by the hydrothermal method. The long axial Co-O coordination bond (Co1‧‧‧O3) can be formed by Co1 and O3.
