Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP [ 2 ] ) in a hexagonal or an orthorhombic, perovskite -like form, and the monoclinic Y 4 Al 2 O 9 (YAM [ 3 ] ).
A perovskite is a crystalline material of formula ABX 3 with a crystal structure similar to that of the mineral perovskite, this latter consisting of calcium titanium oxide (CaTiO 3). [2] The mineral was first discovered in the Ural mountains of Russia by Gustav Rose in 1839 and named after Russian mineralogist L. A. Perovski (1792–1856).
Yttrium, iron, aluminium, and gadolinium garnets (e.g. Y 3 (Fe,Al) 5 O 12 and Y 3 (Fe,Gd) 5 O 12) have important magnetic properties. [15] YIG is also very efficient as an acoustic energy transmitter and transducer. [74] Yttrium aluminium garnet (Y 3 Al 5 O 12 or YAG) has a hardness of 8.5 and is also used as a gemstone in jewelry (simulated ...
Certain transparent materials with a small concentration of neodymium ions can be used in lasers as gain media for infrared wavelengths (1054–1064 nm), e.g. Nd:YAG (yttrium aluminium garnet), Nd:YAP (yttrium aluminium perovskite), [64] Nd:YLF (yttrium lithium fluoride), Nd:YVO 4 (yttrium orthovanadate), and Nd:glass
Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...
A New Mexico woman pleaded guilty to second-degree murder this week after killing her daughter’s teenage boyfriend and then trying to pin the crime on her own son, according to authorities.
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.
