DescriptionLuAG:Ce, Lutetium Aluminum Garnet activated by cerium (chemical formula Lu3Al5O12), is a relatively dense and fast scintillation material. Its density of 6.73 g/cm3 is about 94% of the density of BGO (7.13 g/cm3). Its decay time is much faster (70 ns) than that of BGO (300 ns). This is of advantage in time dependent and coincidence measurements. The wavelength of scintillation emission is about 535 nm, which is ideal for photodiode and avalanche diode readout. The material can also be used for imaging screens, similarly to YAG:Ce. A particular advantage of LuAG:Ce is its higher density resulting in thinner screens with higher spatial resolution. The material is mechanically and chemically stable, and can be machined into a variety of shapes and sizes including prisms, spheres and very thin platesSpecificationParameters of materialsMaterialsCe:LuAGDecay time/ns55Melting Point1975°Refractive Index1.8Density6.67Polishing Specification for Optical GradeⅠOrientation Tolerence< 1°Thickness/Diameter Tolerance±0.10 mmSurface Flatness<(λ-2λ)@632nmWavefront Distortion<(2-4)λ@632nmSurface Quality80/50Parallel10ˊPerpendicular60ˊClear Aperture>90%Chammfer<0.2×45°Polishing Specification for Optical Grade ⅡOrientation Tolerence< 0.5°Thickness/Diameter Tolerance±0.10 mmSurface Flatness<(λ/2-λ/4)@632nmWavefront Distortion<(1-2)λ@632nmSurface Quality60/40Parallel1ˊPerpendicular30ˊClear Aperture>90%Chammfer<0.2×45°Orientation Tolerence< 0.2°Thickness/Diameter Tolerance±0.02 mmSurface Flatness(λ/4-λ/6)@632nmWavefront Distortion<(λ-λ/2)@632nmSurface Quality40/20Parallel45〞Perpendicular20ˊClear Aperture>90%Chammfer<0.2×45°Standard productsProductConcentrationAperture dimensions,mmlength,mmProduct IDPriceCe:LuAG0.01%-0.8%0-550.1-120 Key ParameterKey ParameterHigh-density,good mechnical stability and chemical stabilityRapid decline（70ns）Suitable for reading by photoelectric diode and avalanche diodeGood temperature stability
