Abstract

At e-beam duration of 2-20 ns a shift of free-exciton line to the high-energy area in a pulsed cathodoluminescence spectrum of CVD diamond was observed. Such a shift had the higher value at the shorter e-beam duration. At ≈ 2 ns e-beam and a room temperature the free-exciton line was observed at 5.312±0.009 eV with the corresponding energy of wavevector-conserving phonon close to the energy of transverse acoustic phonon.
