Radiation-induced defects in montebrasite: An electron paramagnetic resonance study of O– hole and Ti3+ electron centers

American Mineralogist, 2020
Montebrasite is a lithium aluminum phosphate mineral with the chemical formula LiAlPO4(Fx,OH1–x) and considered a rare gemstone material when exhibiting good crystallinity. In general, montebrasite is colorless, sometimes pale yellow or pale blue.
