“…[31] It has been suggested that Li + ions in Ce 3+ , Li + -co-doped LuAG do substitute Lu 3+ sites with charge balance attained in part by conversion of Ce 3+ to Ce 4+ and creation of O− hole centers, whereas in Ce 3+ , Li + -co-doped YAG, Li + goes in interstitial position with charge compensation attained by reduction of anion vacancies. [22,29] The behaviour of these Lu-based Accepted Article…”

Development and prospects of garnet ceramic scintillators: A review

“…In a garnet system, in addition to the substitution of matrix cations, the scintillation performance can also be improved by co-doping aliovalent ions, which is called "defect engineering". Usually, lower-valence co-dopants like Mg 2+ , Ca 2+ , Li + , and others will change the defect structure of the materials by altering the charge compensation mechanism or affecting the vacancy concentration in the materials, thereby affecting the scintillation performance [154][155][156][157][158]. Especially in the cerium-doped materials, the low-valence ions can stabilize some of the cerium ions at the tetravalent valence.…”

Modification of Ce3+ luminescence in Li+ and Mg2+ codoped GAGG:Ce scintillators: A comparative study using synchrotron radiation

“…Fine-tuning material properties and designing novel luminescent materials, and crystal engineering strategies form the basis of emerging application innovations [1]. Through structure, composition, and synthesis method links, RE3M5O12 garnets form an enigmatic family of inorganic composites [1][2][3][4][5][6]. With their compositional flexibility, RE3M5O12 From medical imaging to white LED applications and afterglow materials, Ce 3+ doped garnets hold great potential, capturing much attention.…”
