【Substrate Papers】Scintillation and optical properties of undoped and Si-doped β-(AlₓGa₁₋ₓ)₂O₃ crystals grown by the Czochralski method

      Researchers from Astronomy and Informatics Nicolaus Copernicus Univeristy have published a dissertation titled " Scintillation and optical properties of undoped and Si-doped β-(Al_xGa_1-x)₂O₃ crystals grown by the Czochralski method " in Optical Materials.

Abstract

      In this paper we present the results of our recent studies performed on undoped and Si-doped β-(Al_xGa_1-x)₂O₃ crystals grown by the Czochralski method at Leibniz-Institut für Kristallzüchtung in Berlin. The research, including pulse height spectra (with determination of light yield and energy resolution), scintillation time profiles, low-temperature thermoluminescence, and X-ray excited emission spectra recorded as a function of temperature, has been aimed to assess the influence of partial replacing gallium with aluminum on the scintillation properties.
