摘要: The luminescence of single crystalline and powder specimens of β-Ga 2 O 3 has been studied in the temperature range 5–300° K. The investigations were carried out on nominally pure samples and samples doped with various cations. In addition to the intrinsic uv emission a blue and a green emission occurred. On the basis of luminescence and electronic conductivity data the blue emission is ascribed to the recombination of an electron in a V× o or Ga× i center and a hole trapped in a gallium ion vacancy. The data on the green …
