Gadolinium aluminum garnet (GdAG) is a compound with cubic structure used as a matrix material in optics. This paper reviews recent findings in the directions of phosphors, scintillators, and solid-state lasers using GdAG and its derivatives. Challenges in synthesis and application of GdAG-based optical materials are discussed, along with proposed future development directions.
Gadolinium aluminum garnet is a compound with cubic structure composed of Al-O octahedron and Al-O tetrahedron. The chemical formula is Gd3Al5O12 (GdAG). In the field of optics, GdAG is an excellent matrix material, which has led researchers to explore in the direction of phosphors, scintillators and solid-state lasers. In view of many advances in recent years, the recent findings of GdAG and its derivatives in the above three directions are reviewed in this paper. For GdAG phosphors, this paper discusses the preparation technology of phosphors and the key factors affecting the fluorescence performance of phosphors. For GdAG scintillators and solid-state lasers, this paper discusses the factors affecting the porosity grain uniformity of transparent ceramics, and compares the optical properties of single crystal and optical ceramics. Finally, the problems in the synthesis and application of GdAG-based optical materials are discussed, and the future development direction is proposed.
