Infrared cathodoluminescence of AlN

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

Measurements were made of cathode-ray excited infrared luminescence band of AlN powder in the temperature range 110 K to 535 K. The form of the temperature-dependent luminescence band and the temperature dependence of the band half-width were used in the determination of the value of the Huang-Rhys factor (S ≈ 2) as well as of the frequency of phonons (441 cm−1) interacting with electron transition. A discussion is presented of the possibility of interaction between an infrared luminescence centre and branch of natural transverse acoustic vibrations of the AlN lattice.
