The films were grown by a microwave plasma enhanced chemical vapour deposition system. The film quality and surface morphology were characterised by Raman spectroscopy and scanning electron microscopy, respectively. For selected samples, the temperature behaviour of steady-state PL emission spectra was studied within the range 11 ÷ 300 K as well. The PL properties are related to the film growth temperature. We found that 800 °C is the optimal growth temperature, at which the highest intensity of the Si-V centre PL was observed. For all the samples, the blue shift in the position of the Si-V centre PL zero-phonon line is observed with decreasing temperature, which is attributed to the effects of lattice contraction and quadratic electron–phonon coupling. The zero-phonon line narrowing is discussed regarding vibrations of the perturbed lattice.
