Metastability of Mn${}^{3+}$ in ZnO driven by strong $d$(Mn) intrashell Coulomb repulsion: experiment and theory

A. Ciechan, H. Przybylińska, P. Bogusławski +5

Depopulation of the Mn${}^{2+}$ state in ZnO:Mn upon illumination, monitored by quenching of the Mn${}^{2+}$ EPR signal intensity, was observed at temperatures below 80~K. Mn${}^{2+}$ ph…
