“…The hot-injection method, ligand-assisted reprecipitation (LARP) and reverse microemulsion methods are used to synthesise 0D nanocrystals. Hot-injection or the organometallic hightemperature colloidal method (Wu et al, 2011) is based on a precursor injection into a hot solution containing other precursors, organic ligands and a high boiling solvent. Though it is one of the most common techniques, this method's main requirements are high temperature and an inert atmosphere.…”

In recent decades, many technological advances have been enabled by nanoscale phenomena, giving rise to the field of nanotechnology. In particular, unique optical and electronic phenomena occur on length scales less than 10 nanometres, which enable novel applications. Halide perovskites have been the focus of intense research on their optoelectronic properties and have demonstrated impressive performance in photovoltaic devices and later in other optoelectronic technologies, such as lasers and light-emitting diodes. The most studied crystalline form is the three-dimensional one, but, recently, the exploration of the low-dimensional derivatives has enabled new sub-classes of halide perovskite materials to emerge with distinct properties. In these materials, low-dimensional metal halide structures responsible for the electronic properties are separated and partially insulated from one another by the (typically organic) cations. Confinement occurs on a crystal lattice level, enabling bulk or thin-film materials that retain a degree of low-dimensional character. In particular, quasi-zero dimensional perovskite derivatives are proving to have distinct electronic, absorption, and photoluminescence properties. They are being explored for various technologies beyond photovoltaics (e.g. thermoelectrics, lasing, photodetectors, memristors, capacitors, LEDs). This review brings together the recent literature on these zero-dimensional materials in an interdisciplinary way that can spur applications for these compounds. The synthesis methods, the electrical, optical, and chemical properties, the advances in applications, and the challenges that need to be overcome as candidates for future electronic devices have been covered.

As typical II–VI ternary alloyed chalcogenides, CdSeS nanostructures have attracted intensive worldwide attention due to their excellent tunable optical properties based on quantum confinement effect and optical nonlinear phenomenon. Because CdSeS-based nanostructures have presented a great potential for applications in biomedicine and optoelectronic devices, different synthesis methods have been proposed to prepare CdSeS-based nanostructures with divergent optical properties to meet the needs of those applications, such as fluorescent labeling,in vivoimaging, waveguides, and solar cell. In this review, the tricks, advantages, and disadvantages of all these synthesis methods were discussed, including hot-injection synthesis, one-pot noninjection synthesis, microwave irradiation, solvothermal synthesis, template-assisted electrodeposition, thermal evaporation, and pulsed laser deposition. Special emphasis was put on those methods that are safe, economic, environment-friendly, and suitable for large-scale production of alloyed CdSeS nanostructures with high photoluminescence, high stability, and low/no cytotoxicity.
