Investigated nanocrystalline (grain size < 100 nm) submicron thick GaN, AlN and BN layers were produced on Si substrates by means of reactive crystallization from impulse plasma (RPP CVD method), while diamond-like carbon (DLC) films were obtained in the course of radio frequency (13.56 MHz) chemical vapor deposition (RF CVD) process. In our previous works (e.g. [1-3]) we presented results of the studies of their optical (refractive index value, absorption edge value), electronic (resistivity, dielectric constant, state of the substrate/layer interface) as well as low-temperature photoluminescent properties . Attempts of correlating structural, optical and electronic properties of discussed films with their photoluminescent characteristics were also undertaken.
