在1650 °C下，采用一种简单易行的制备方法制备了一种新型的GGAG/YAG层状复合闪烁陶瓷。本工作采用的氧烧-热等静压法可以显著缩短闪烁陶瓷的制备周期。该陶瓷具有规则的晶粒显微结构。复合陶瓷界面平整、光滑。制备的Ce：GGAG/Cr：YAG层状复合陶瓷在激发下可发射波长为500 ~ 750 nm的宽范围光子。积分光谱由Cr：YAG和Ce：GGAG的发射光子和Ce：GGAG陶瓷层发射光子激发的Cr：YAG发射光三部分组成。该方法对全光谱闪烁/发光陶瓷的制备和光谱设计具有重要意义。
A novel layered GGAG/YAG composite scintillation ceramic can be prepared at 1650 °C using an easily accessible preparation procedure. The oxygen sintering-hot isostatic pressing method implemented in this work can significantly shorten the preparation period of scintillation ceramics. The ceramic exhibits regular grain microstructure. Interface of the composite ceramic is clean and straight. As prepared, the layered Ce:GGAG/Cr:YAG composite ceramic can emit a broad range of photons with wavelength from 500 to 750 nm under excitation. The integral spectra is composed of three parts: emitted photons of Cr:YAG and Ce:GGAG and emitted light of Cr:YAG excitated by the photons emitted by the Ce:GGAG ceramic layerprepared by the proposed method. The method accomplished in this work can significantly improve the exploration of full spectrum scintillation/luminescence ceramics preparation and spectra designation.
