Crystal growth and scintillation properties of YAG:Ce <sup>3+</sup> for γ and α detection
© 2018 Elsevier Ltd A bulk single crystal of yttrium aluminum garnet (Y 3 Al 5 O 12 :Ce 3+ , YAG:Ce 3+ ) with good optical quality and free of cracks has been grown successfully by the Kyropoulos method. The dimension of the as grown crystal boule was Ø 20 × 30 cm 3 . The cut and polished crystal s...

Kaewkhao Physics and Astronomy © 2018 Elsevier Ltd A bulk single crystal of yttrium aluminum garnet (Y 3 Al 5 O 12 :Ce 3+ , YAG:Ce 3+ ) with good optical quality and free of cracks has been grown successfully by the Kyropoulos method. The dimension of the as grown crystal boule was Ø 20 × 30 cm 3 . The cut and polished crystal sample of dimensions 1 × 1 × 0.5 cm 3 was used for further measurements. The phase purity was confirmed by powder X-ray diffraction pattern analysis. The scintillation properties, such as X-ray emission spectrum, pulse height spectra, energy resolution, and scintillation decay time, were investigated using a 137 Cs γ-ray source. The recorded X-ray emission spectrum shows a broad band between 500 and 700 nm with a peak at around 540 nm, which is attributed to the 5d-4f transition of the Ce 3+ ion. The pulse-shape discrimination (PSD) of α and γ signals in a YAG:Ce 3+ crystal has been studied by using different pulse shapes. The grown YAG:Ce 3+ crystal which is non-hygroscopic, chemically inert, fast inorganic scintillator could be used for radiation detection application in nuclear, and high energy physics. 2019-03-18T02:25:44Z 2019-03-18T02:25:44Z 2019-03-01 Journal 18729800 09698043 2-s2.0-85059080581 10.1016/j.apradiso.2018.12.011 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85059080581&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/63756 |
