Comparative Analysis of Properties of Aluminum-Based and Silicon-Based Oxyanate Scintillation Crystals
摘要
Abstract
Scintillation crystals are a class of crystalline materials that can generate visible light under the action of high-energy particles or high-energy radiation,and convert the kinetic energy of high-energy particles into light energy.This study takes two types of scintillation crystals,Ce∶LuYSiO5(Ce∶LYSO)and Ce∶Y3 Al5 O12(Ce∶YAG),as the research objects and conducts systematic performance tests.For the light yield,the measurement was conducted using the ORTEC4518 scintillation detector system,and the results showed that the light yield of the Ce∶YAG crystal is 52300 ph/MeV,while that of Ce∶LYSO crystal is 27700 ph/MeV.In terms of detection limits,the measurement was performed using the Lanjing Technology LJ-WF300 low-background multi-channel γ-spectrometer.The results showed that the minimum detectable X-ray dose rate of the Ce∶LYSO crystal is 92 μGy/s,and that of the Ce∶YAG crystal is 95 μGy/s.This characteristic indicates that both crystals exhibit high sensitivity to low-dose X-rays,making them suitable for low-dose radiation detection scenarios.The above data provides an important basis for the application of Ce∶LYSO and Ce∶YAG scintillation crystals in the radiation imaging field.关键词
