摘要：
The effect of sintering additives of B, Mg, Zr and Si compounds on the morphology and luminescent properties of Gd1.5Y1.5Al2Ga3O12:Ce (GYAGG:Ce) ceramic quaternary garnets produced by free sintering has been studied. The microstructure of the ceramics, their optical absorption, steady-state luminescence spectroscopy and kinetics, as well as scintillation parameters upon excitation by alpha-particles (E = 5.5 MeV) were studied. Analysis of the results allows to conclude that additives based on Zr improve the optical and spectral properties of the ceramic material of the given composition.
