Cathodoluminescence of Ga_2(S_<0.73>Te_<0.27>)_3

概要

論文の詳細を見る
Intense and stable orange cathodoluminescence emission is discovered in Ga_2(S_<0.73>Te_<0.27>)_3 at room temperature. Solid solutions of the Ga-S-Te system were grown by the closed tube chemical transport method using GaI_3 as a transporting agent. Intensity of the cathodoluminescence increases linearly with an incident electron beam current, and with an accelerating voltage. The line-shape of the spectrum is broad and independent of the condition of the incident beam. The peak wavelength is 6900Å and corresponds to the energy gap, 1.80 eV, obtained from the optical transmission measurement.
