In this letter the study of Li-doped zinc oxide by electron paramagnetic resonance method is described.A signal observed atg=2.013,g₁=1.955 on the degassed sample at 923K was designated toF_s⁺ centers(surface oxygen ion vacancies with a single trapped electron).When the sample was quenched from 1003K into liquid oxygenat 77K under 24 KPa O₂,[Li⁺O^-] ion pairs valued at g=2.026 andg=2.003 with superhyperfine constant a=2.0G,which resulted from ⁷Li nucleus,formed at Li⁺-substitutional site in ZnO lattice.A probable mechanism of [Li⁺O^-]ion pair formation was proposed.
