Perovskite (pronunciation: /pÉËrÉvskaÉªt/) is a calcium titanium oxide mineral composed of calcium titanate, with the chemical formula Ca Ti O 3.he mineral was discovered in the Ural Mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist Lev Perovski (1792â1856). It lends its name to the class of compounds which have the same type of crystal structure as CaTiO 3 (XII A 2+ VI B 4+ X 2â 3) known as the perovskite structure.
The perovskites that were used to make the LEDs are known as organometal halide perovskites, and contain a mixture of lead, carbon-based ions and halogen ions known as halides. These materials dissolve well in common solvents, and assemble to form perovskite crystals when dried, making them cheap and simple to make.he team is now looking to increase the efficiency of the LEDs and to use them for diode lasers, which are used in a range of scientific, medical and industrial applications, such as materials processing and medical equipment. The first commercially-available LED based on perovskite could be available within five years.
