Low-coordinated oxygen sites on MgO surfaces

Lead Institution
University of Erlangen-Nuremberg
Principal Investigator
Oliver Diwald
Project type
Exploratory Research
Recently, we have measured the pphotoluminescnece of MgO particles as a function of the excitation wavelength (4.6 eV and 5.1 eV) and observed two emission bands at 3.3 and 3.4 eV. According to…

Excitation of Surface Excitons in the Nanoscale Calcium Oxide Surface

Lead Institution
University of Erlangen-Nuremberg
Principal Investigator
Oliver Diwald
Project type
Exploratory Research
Optical absorption and photoluminescence emission properties of dehydroxylated MgO and CaO CVD-grown nanocrystals have recently been undertaken with respect to particle morphology and size. On MgO…

Site-specific Surface Excitation of Calcium Oxide "Nanocubes"

Lead Institution
University of Erlangen-Nuremberg
Principal Investigator
