Perovskite nanocrystals possess numerous unique attributes: defect tolerance, high quantum yield, fast rates of radiative decay and narrow emission line width in weak confinement, which make them ideal candidates for a variety of optoelectronic applications.
Perovskite materials exhibit many interesting and intriguing properties from both the theoretical and the application point of view. Colossal magnetoresistance , ferroelectricity , superconductivity , charge ordering , spin dependent transport, high thermopower and the interplay of structural, magnetic and transport properties are commonly ...
Perovskite (pronunciation: / p ə ˈ r ɒ v s k aɪ t /) is a calcium titanium oxide mineral composed of calcium titanate (chemical formula Ca Ti O 3).Its name is also applied to the class of compounds which have the same type of crystal structure as CaTiO 3, known as the perovskite structure, which has a general chemical formula A 2+ B 4+ (X 2−) 3.

Methylammonium lead halides (MALHs) are solid compounds with perovskite structure and a chemical formula of [CH 3 NH 3] + Pb 2+ (X −) 3, where X = Cl, Br or I. They have potential applications in solar cells, [2] lasers, light-emitting diodes, photodetectors, radiation detectors, [3] [4] scintillator, [5] magneto-optical data storage [6] and ...
Another application that takes advantage of the extraordinary photostability of quantum dot probes is the real-time tracking of molecules and cells over extended periods of time. [81] Antibodies , streptavidin , [ 82 ] peptides , [ 83 ] DNA , [ 84 ] nucleic acid aptamers , [ 85 ] or small-molecule ligands [ 86 ] can be used to target quantum ...
Sun et al. developed two polymorphic organometallic nanocrystals formed from platinum (II)-β-diketonate complexes demonstrated light harvesting and photoluminescent properties. [27] Zeolite nanocrystals that allow for the supramolecular organization of organic dye molecules have also been designed for light harvesting. [23]
Megalibraries have identified catalysts for use in the clean energy, automotive and chemical industries, [1] and researchers are exploring new ways to expand their applications. When the nanoparticles in a megalibrary are first synthesized, their properties, such as crystal structure and chemical composition, may be unknown.
Aurivillius phases are a form of perovskite represented by the general formulae is (Bi 2 O 2)(A n−1 B n O 3n+1) (where A is a large 12 co-ordinate cation, and B is a small 6 co-ordinate cation).
