Summary: Water-soluble CdTe colloidal QDs with different emissions were synthesized using 3-MPA as a stabilizing agent and varying growth times. The red-shift in absorption and emission spectra indicated an increase in particle size. XRD and FTIR analysis confirmed the crystal structure and surface capping effect of the QDs. HRTEM and EDX analysis provided insights into the morphology and elemental composition of the QDs. The green emitting CdTe QDs showed excellent luminance and were found to be efficient fluorescent probes for fluorescence imaging of onion epidermal cells.

Summary: This study proposed a powerful ligand engineering strategy to eliminate surface defects and aggregation of CsPbBr3nanocrystals (NCs), improving their colloidal stability and fluorescence. The as-synthesized NCs with amphiphilic polymer-modified ligands exhibited high photoluminescence intensity and stability. Furthermore, the NCs showed enhanced water, photostability and thermal stability. Additionally, a colorimetric sensor based on these NCs was successfully constructed for the detection of chloride ions in sweat, enabling rapid, visual and accurate detection.

Summary: By introducing ytterbium acetate (Yb(OAc)3), this study achieved a significant enhancement in sensitivity for Cu2+ detection using CsPbCl3 perovskite nanocrystals. The formed 1D CsPbCl3 NWs facilitated rapid electron transport and reduced defect density, leading to efficient inhibition of undesired charge traps. The Yb(OAc)3 passivated CsPbCl3 NWs exhibited efficient luminescence quenching and achieved a low detection limit of 0.06 nM in the Cu2+ detection window.

Summary: Recently, CsPbX3 (X= Cl, Br, I) nanocrystals (NCs) have shown promise for optoelectronic applications, particularly in bioimaging, due to their superior photophysical properties. However, their poor stability in aqueous media poses a challenge. To address this, we developed a fast and reproducible synthesis method that coats CsPbBr3 NCs with long-chained organic ligands/polymers. Among them, polyvinylpyrrolidone (PVP) encapsulated NCs exhibit highly luminescent properties and improved stability when incorporated with n-isopropyl acrylamide (NIPAM). These polymer-coated NCs demonstrate better water stability, smaller particle size, uniform distribution, higher structural stability, and increased dispersivity, making them suitable as fluorescent probes for live cell imaging. The dosage of Pb-ions in the polymer-coated NCs is calculated to be below 5 μg/mL, enabling safe live cell imaging. This work provides valuable insights for expanding the application of these NCs in bioimaging with higher sensitivity.

Summary: Recent research has shown that low-dimensional materials, such as quantum dots and core-shell quantum dots, exhibit strong nonlinear optical behavior and have potential applications in photo-electronics, photovoltaic nonlinear optics, light-emitting diode fabrication, and laser protections. Variations in core-shell shape and size, as well as the chemical composition of quantum dots, define their enhanced nonlinear optical properties. Specific nonlinear optical properties, such as nonlinear refraction, optical limiting, saturable absorption, and reverse saturable absorption of CdTe and CdSe quantum dots, along with core-shell quantum dots and their applications, were assessed in this study.

Summary: The synthesis, luminescent, and structural properties of stable perovskite-type (Cs1-xRbx)(4)PbBr6 (R = Cs, Rb) nanocrystals are shown for the first time. Cs4PbBr6 and CsPbBr3 perovskite crystals precipitate in the ZnO-Na2O-B2O3-GeO2 glass matrix in the absence of rubidium. As the rubidium content increases, the precipitation of (Cs,Rb)(4)PbBr6 nanocrystals is replaced by Rb4PbBr6 nanocrystals nucleation. Nucleated nanocrystals exhibit intense green luminescence, which shifts to the blue region with an increase of the rubidium content, and the luminescence quantum yield and average decay time also increase.

Summary: In order to address the issue of poor structural stability of lead halide perovskite nanocrystals (NCs), a novel strategy for synthesizing stable CsPbBr3@SiO2 NCs is designed. The method utilizes the hydrolytic polycondensation of (3-aminopropyl)triethoxysilane (APTES) in the presence of ionic liquids (ILs). This approach effectively resolves the problems of fluorescence quenching and undesirable agglomeration, resulting in CsPbBr3@SiO2 NCs with high photoluminescence quantum yield and excellent stability.
