Electron Paramagnetic Resonance Investigations of ZnSe:Mn Nanocrystals

Colloidal nanocrystals of ZnSe doped with Mn 2 + were synthesized in non - polar medium using hot - injection technique. Obtained samples were characterized by means of photoluminescence and absorption spectroscopies. To confirm the incorporation of Mn 2 + impurity and to reveal its state and locali...

Description
Summary:Colloidal nanocrystals of ZnSe doped with Mn 2 + were synthesized in non - polar medium using hot - injection technique. Obtained samples were characterized by means of photoluminescence and absorption spectroscopies. To confirm the incorporation of Mn 2 + impurity and to reveal its state and localization, electron paramagnetic resonance (EPR) spectroscopy was employed. As a result, EPR spectra were analyzed and hyperfine splitting constant and g - factor for Mn 2 + dopant were determined.
