Diversification of pulse cycle numbers proportional to the AlN films thickness using PALE technique on c-plane sapphire substrate were carried out via MOCVD. It was experiential that the structural features of as-deposited AlN films were significantly impinged on the film thickness where the highest number of pulse cycles (1050 pairs) present the lowest (0 0 0 2)-symmetry and (1 0-1 2)-asymmetry XRC analysis, manifest a decrease of threaded dislocation density. The XPS spectra present a low foreign impurities inclusion on the AlN film surface was achieved even at highest cycle number by engaging the PALE growth technique. The spectroscopy of PL and UV-Vis NIR were employed to probe the optical characteristics involving the absorption and their band-edge transitions. In both optical spectroscopies, the room temperature of band-edge emission lines has expressed a significant interconnection between the structural and optical quality of as-deposited AlN films at different pulse cycle numbers.
