“…Generally, two wet chemical methods have been used for the preparation of PQDs: hot injection (HI) − and ligand-assisted reprecipitation (LARP). , The HI approach relies on injection of a presynthesized precursor into an organic solvent containing another precursor ligands under high temperature (140–200 °C) and inert atmospheres, followed by quenching of the reaction with an ice bath. For example, HI was adopted to prepare CsPbX 3 PQDs by Protesescu et al in 2015 for the first time .…”

Metal halide perovskite quantum dots (PQDs) and perovskite magic sized clusters (PMSCs) exhibit interesting size- and composition-dependent optoelectronic properties that are promising for emerging applications including photovoltaic solar cells and light-emitting diodes (LEDs). Much work has focused on developing new synthesis strategies to improve their structural stability and property tunability. In this paper, we review recent progress in the synthesis and characterization of PQDs and PMSCs, with a focus on the impact of different molecular ligands on their surface passivation and interconversion. Moreover, the effect of capping ligands on ion exchange during synthesis and doping is discussed. Finally, we present some perspectives on challenges and opportunities in fundamental studies and potential applications of both PQDs and PMSCs.

“…They combine the favorable optical properties of fluoride glasses with the higher mechanical and thermal stability of phosphate glasses. Aluminum-containing fluoride phosphate glasses − have attracted considerable attention as matrices for rare-earth dopants for active lasers, amplifier glasses, and for photoluminescence in the visible region. − In addition, nanoparticle-containing systems, inorganic–organic hybrid systems, and biomaterials are being studied . The goal of tailoring the particular properties of these attractive glasses requires a comprehensive understanding of their structural organization.…”

The local structure of the model glasses (NaPO 3 ) 1−x -(AlF 3 ) x (0 ≤ x ≤ 0.4), prepared by standard melt-cooling, was extensively investigated by high-resolution solidstate nuclear magnetic resonance (NMR) including advanced double-resonance techniques. This glass system offers the opportunity of studying five different heteronuclear distance correlations (Na−F, Na−P, P−F, Al−F, and P−Al) by 10 distinct double-resonance experiments, involving all of the constituent elements present. 27 Al MAS-NMR data indicate that aluminum is predominantly six-coordinated. According to 27 Al{ 31 P} and 27 Al{ 19 F} rotational-echo double-resonance (REDOR) spectroscopic results, two to three Al−F and three to four Al−O−P linkages occur in these glasses, independent of composition x. 19 F MAS-NMR spectra show the presence of terminal P-bound and Al-bound fluorine species. A small amount of fluorine bridging to two aluminum octahedra, which could be assigned based on 19 F{ 27 Al} and 19 F{ 31 P} REDOR experiments, was also detected. 19 F{ 23 Na} REDOR experiments indicate that the Al-bound terminal F atoms interact significantly more strongly with sodium ions than the P-bonded terminal F atoms, which is consistent with local charge considerations. On the basis of the detailed quantitative dipole−dipole coupling information obtained, a comprehensive structural model for these glasses is presented.
