Organometal halide perovskites (hybrid perovskites) contain an anionic metal-halogen-semiconducting framework and charge-compensating organic cations. As hybrid materials, they combine useful properties of both organic and inorganic materials, such as plastic mechanical properties and good electronic mobility related to organic and inorganic material, respectively. They are prepared from abundant and low cost starting compounds. The perovskite stoichiometry is associated with the dimensionality of its inorganic framework, which can vary from three to zero, 3D consisting of corner-sharing MX 6 octahedra, and 0D consisting of isolated octahedra. Small-sized organic cations can fi t into the MX 6 octahedra of the 3D framework and in all dimensions organic cations surround the inorganic framework. Regarding the low dimensionality in the material, this refers to at least one of its dimensions being shorter than approximately 100 nanometers. These materials should be considered as genuine nanomaterials or as bulk materials depending on whether they have three or less than three dimensions on the nanoscale, respectively. In principle, hybrid perovskite nanoparticles can be prepared with different shapes and with inorganic framework dimensionalities varying from 0D to 3D, and this also applies to the bulk material. This report is mainly focused on the unique properties of organometal halide perovskite nanoparticles.

“…According to the studies in Ref. [8,[15][16][17][18][19], the enhancement is due to the unusual alternate organic-inorganic layered structure enabling the exciton state to be very stable even at room temperature.…”

“…The two dimensionality of the layered structure combined with the dielectric confinement effect enables the formation of a stable exciton with a large binding energy of several hundred meV in the inorganic semiconductor layer of PbX 4 [11][12][13][14]. Several attractive optical properties are induced by the exciton presence such as efficient photoluminescence at room temperature [15][16][17][18][19]. As a consequence, their unusual semiconducting properties have been widely studied and used for photoluminescence materials, thin-film field-effect transistors, electroluminescent devices, etc.…”

Three‐dimensional (3 D) perovskite has attracted a lot of attention owing to its success in photovoltaic (PV) solar cells. However, one of its major crucial issues lies in its stability, which has limited its commercialization. An important property of organic–inorganic perovskite is the possibility of forming a layered material by using long organic cations that do not fit into the octahedral cage. These long organic cations act as a “barrier” that “caps” 3 D perovskite to form the layered material. Controlling the number of perovskite layers could provide a confined structure with chemical and physical properties that are different from those of 3 D perovskite. This opens up a whole new batch of interesting materials with huge potential for optoelectronic applications. This Minireview presents the synthesis, properties, and structural orientation of low‐dimensional perovskite. It also discusses the progress of low‐dimensional perovskite in PV solar cells, which, to date, have performance comparable to that of 3 D perovskite but with enhanced stability. Finally, the use of low‐dimensional perovskite in light‐emitting diodes (LEDs) and photodetectors is discussed. The low‐dimensional perovskites are promising candidates for LED devices, mainly because of their high radiative recombination as a result of the confined low‐dimensional quantum well.
