A novel layered GGAG/YAG composite scintillation ceramic can be prepared at 1650 degrees 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. (C) 2016 Elsevier Ltd.
