Improving the Solubility of Mn and Suppressing the Oxygen Vacancy Density in Zn<sub>0.98</sub>Mn<sub>0.02</sub>O Nanocrystals via Octylamine Treatment
No full textZn<sub>0.98</sub>Mn<sub>0.02</sub>O nanocrystals were
synthesized
by the wet chemical route and were treated with different content
of octylamine. The environment around Mn and the defect type and concentration
were characterized by photoluminescence, Raman, X-ray photoelectron
spectroscopy, and X-ray absorption fine structure. It is found that
N codoping effectively enhances the solubility of Mn substituting
Zn via reducing donor binding energy of impurity by the orbital hybridization
between the N-acceptor and Mn-donor. On the other hand, the O atoms
released from MnO<sub>6</sub> and the N ions from octylamine occupy
the site of oxygen vacancies and result in reduction of the concentration
of oxygen vacancies in Zn<sub>0.98</sub>Mn<sub>0.02</sub>O nanocrystals
