This review focuses on modern scintillators, the heart of ionizing radiation detection with applications in medical diagnostics, homeland security, research, and other areas. The conventional method to improve their characteristics, such as light output and timing properties, consists of improving in material composition and doping, which are intrinsic to the material. On the contrary, we review recent advancements in cutting-edge approaches to shape scintillator characteristics via photonic and metamaterial engineering, which are extrinsic and introduce controlled inhomogeneity in the scintillator's surface or volume.

- Gadolinium-yttrium-aluminum-gallium garnets (GYAGG) were developed as ceramics doped with Eu, Tb, and Ce for use as long-wavelength phosphors in bright white light sources using cathodoluminescence (CL).
- The light yield (LY) of the Tb-doped ceramics significantly outperformed the traditional YAG:Ce phosphor, although adding Eu to shift color reduced the LY to that of YAG:Ce.
- Mixing Tb- and Eu-doped GYAGG powders could enhance LY further, with the Gd sublattice aiding excitation transfer, and the phosphors' chromaticity can be adjusted by changing the concentration ratios of Tb and Eu.
This review article considers the latest developments in the field of inorganic scintillation materials. Modern trends in the improvement of inorganic scintillation materials are based on engineering their features at the nanoscale level. The essential challenges to the fundamental steps of the technology of inorganic glass, glass ceramics, and ceramic scintillation materials are discussed.
