Abstract
⺠Zn0.92Mn0.08O nanoparticles were synthesized by co-precipitation technique, and annealed in H2, CO, Ar and O2, respectively. ⺠Room temperature ferromagnetism was found in sample annealed in H2 and CO, respectively. ⺠The higher the carrier concentration, the larger the shift to the high energy direction in the optical absorption spectra. ⺠Singly ionized oxygen vacancies play an important role in the origin of ferromagnetism. ⺠We decomposed visible emission peaks into the green emission band and yellow emission band by Gaussian fitting.
