ROS generation kinetics of Y2O3:Eu@SiO2 as a function of X-ray absorbed energy. (A) 1O2 measured by DPBF; (B) O2•- measured by DHE; and (C) •OH measured by 3-CCA. (D) ROS generation of Y2O3:Eu@SiO2 before (light grey) and after bubbling N2 gas (dark grey) with 10 Gy X-ray. The samples of Y2O3:Eu@SiO2 without X-ray irradiation is as control group (checkered).
