چکیده
Lead-free copper halide perovskite nanocrystals (NCs) are emerging materials with excellent photoelectric properties. Herein, we present a colloidal synthesis route for orthorhombic Cs2CuCl4 NCs well-defined cubic shape and an average diameter of 24 ± 2.1 nm. The exhibited bright, deep blue photoluminescence, which was attributed to the Cu(II) defects. In addition, passivating by Ag+ could effectively improve photoluminescence quantum yield (PLQY) environmental stability.

Colloidal synthesis of germanium nanocrystals
In this study, colloidal germanium nanocrystals were synthesized by a simple and novel method, and their optical properties were also studied. Polyvinyl alcohol (PVA) as a surface modifier was used to control the optical properties of colloidal Ge nanocrystals. Fourier transform infrared spectroscopy (FTIR) analysis was performed to identify the various functional groups present in the sample. ...
متن کاملSynthesis and properties of colloidal lanthanide-doped nanocrystals
Colloidal solutions and redispersible powders of nanocrystalline, lanthanide-doped phosphates and vanadates have been prepared in high-boiling coordinating solvents or by hydrothermal means in aqueous solution. Highly crystalline materials were obtained by both methods despite the low temperature of 2008C applied during the synthesis. The materials have been characterized by using high-resoluti...
