Red light scintillation ceramic and preparation method and application thereof
The invention discloses red light scintillation ceramic and a preparation method and application thereof, the chemical formula of the red light scintillation ceramic is [Lu0. 5Gd. 0.5-xEux] 2O3, the preparation method comprises the following steps: S1, carrying out compression molding on powder containing Lu2O3, Gd2O3, Eu2O3 and a sintering aid to obtain a biscuit; and S2, pre-sintering the biscuit obtained in the step S2, carrying out vacuum sintering, and annealing to obtain the red light scintillation ceramic. The series of red light scintillation ceramics have the characteristics of high density, steady-state luminescence, excellent light output and good irradiation stability. And the scintillation transparent ceramic is stable in structure, so that long-term stable work under X-ray irradiation can be realized.
本申请公开了一种红光闪烁陶瓷及其制备方法和应用，所述红光闪烁陶瓷的化学式为[Lu0.5Gd0.5‑xEux]2O3，制备方法包括：S1、将含有Lu2O3、Gd2O3、Eu2O3、烧结助剂的粉体压制成型后获得素坯；S2、将步骤S2获得的素坯预烧结、真空烧结、退火，获得所述红光闪烁陶瓷。该系列红光闪烁陶瓷具有高密度、稳态发光特性、优异的光输出、良好的辐照稳定性。并且由于闪烁透明陶瓷的结构稳定，可以实现在X射线照射下的长期稳定工作。
