Low-temperature photoluminescence in NixMg1−xO nanocrystals

Low-temperature photoluminescence in NixMg1−xO nanocrystals

A study of the photoluminescence and photoluminescence excitation spectra of NixMg1−xO nanocrystals, at low-temperatures. We examine the processes of concentration quenching and supposed mechanisms of energy migration in NixMg1−xO. It is shown that the edge energies of the charge-transfer transition...

Zusammenfassung:A study of the photoluminescence and photoluminescence excitation spectra of NixMg1−xO nanocrystals, at low-temperatures. We examine the processes of concentration quenching and supposed mechanisms of energy migration in NixMg1−xO. It is shown that the edge energies of the charge-transfer transitions in NixMg1−xO (x = 0.008) and NiO are practically identical.
