Lutetium Aluminum Garnet activated by Cerium is a relatively dense, mechanically and chemically stable scintillation material used for photodiode and avalance diode readouts. Due to its higher density, LuAg:Ce results in screens that are thinner and that have higher spatial resolution than those made with YAG:Ce. American Elements can also produce LuAg:Ce in a variety of shapes and sizes including prisms, spheres and very thin plates.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Lutetium is a Block F, Group 3, Period 6 element. The number of electrons in each of Lutetium's shells is 2, 8, 18, 32, 9, 2 and its electronic configuration is [Xe] 4f¹⁵ 5d¹ 6s². In its elemental form lutetium's CAS number is 7439-94-3. The lutetium atom has a radius of 171.8.pm and it's Van der Waals radius is unknown. Lutetium is not toxic. Lutetium is the last member of the rare earth series. Lutetium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Unlike most rare earths it lacks a magnetic moment. It also has the smallest metallic radius of any rare earth. It also has the smallest metallic radius of any rare earth. It is perhaps the least naturally abundant of the lanthanides. It is the ideal host for x-ray phosphors because it produces the densest known white material, lutetium tantalate (LuTaO4). It is utilized as a dopant in matching lattice parameters of certain substrate garnet crystals, such as indium-gallium-garnet (IGG) crystals due its lack of a magnetic moment.Lutetium is the last member of the rare earth series.

The name Lutetium originates from the Latin word Lutetia meaning Paris. See Lutetium research below.

Aluminum is a Block P, Group 13, Period 3 element. The number of electrons in each of Aluminum's shells is 2, 8, 3 and its electronic configuration is [Ne] 3s² 3p¹. In its elemental form aluminum's CAS number is 7429-90-5. The aluminum atom has a radius of 143.2.pm and it's Van der Waals radius is 200.pm. Aluminum is the most abundant metal in the earth's crust. Aluminum is not known to be harmful but ingestion may cause Alzheimer's disease.Aluminum is a silvery-white metal that possesses many desirable characteristics. It is light, nonmagnetic and nonsparking. It stands second among metals in the scale of malleability, and sixth in ductility. It is extensively used in many industrial applications where a strong, light, easily constructed material is needed. Although it's electrical conductivity is only about 60% that of copper, it is used in electrical transmission lines because of its light weight. Pure aluminum is soft and lacks strength, but alloyed with small amounts of copper, magnesium, silicon, manganese, or other elements impart a variety of useful properties. These alloys are of vital importance in the construction of modern aircraft and rockets. Aluminum, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat. They are used to coat telescope mirrors. Aluminum is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.

Cerium is a Block F, Group 3, Period 6 element. The number of electrons in each of Cerium's shells is 2, 8, 18, 19, 9, 2 and its electronic configuration is [Xe]4f² 6s². In its elemental form cerium's CAS number is 7440-45-1. The cerium atom has a radius of 182.5.pm and it's Van der Waals radius is 181.pm. Cerium is moderately toxic. Cerium is one of the products manufactured and distributed under the tradename AE Rare Earths. Cerium is the most abundant of the rare earths metals. It is characterized chemically by having two valence states , the +3 cerous and +4 ceric states. The ceric state is the only non-trivalent rare earth ion stable in aqueous solutions.It is, therefore, strongly acidic and moderately toxic. It is also a strong oxidizer.The cerous state closely resembles the other trivalent rare earths. The numerous commercial applications for cerium include metallurgy, glass and glass polishing, ceramics, catalysts, as the electrolyte for solid oxide fuel cells when doped with yttrium, gadolinium or samarium and in phosphors. In steel manufacturing it is used to remove free oxygen and sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony. It is considered to be the most efficient glass polishing agent for precision optical polishing. It is also used to decolor glass by keeping iron in its ferrous state. The ability of cerium-doped glass to block out ultra violet light is utilized in the manufacturing of medical glassware and aerospace windows. It is also used to prevent polymers from darkening in sunlight and to suppress discoloration of television glass. Cerium was first discovered by W. von Hisinger in 1903. The element was named after the asteroid Ceres. See Cerium research below.
