ABSTRACT

Effect of doping with europium on the shape of the spectra of emission from structures with quantum wells based on InxGa1−xN/GaN, on the mechanism of doping, and the intensity of emission caused by intracenter f-f transitions in Eu is studied. According to the data of Mössbauer spectroscopy, the doping Eu impurity can have the charge state of the impurity ion of Eu2+ and Eu3+ or Eu3+ only. In the case where the charge state of the impurity ion is Eu3+, emission related to the intracenter transitions 5D0−7F2 (λ = 6220 Å) is observed. If the impurity ion can be found in the charge states Eu2+ and Eu3+, the emission related to the intracenter transitions characteristic of both Eu2+ and Eu3+ is not observed. More... »
