abstract = "The paper presents the results of 6H-SiC nanocrystals (NCs) characterization using atomic force microscope (AFM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and photoluminescence spectroscopy techniques. XRD study shows the investigated porous 6H-SiC layers contain inclusions of 4H-SiC and 15R-SiC polytypes. Photoluminescence study of porous SiC layers with different thicknesses and SiC NC sizes (50-250 nm) reveals the intensity stimulation of exciton related PL bands in different SiC polytypes. The intensity enhancement for excitonrelated PL bands is attributed to the exciton recombination rate increasing due to the realization of exciton-polariton effects in big size SiC NCs of different polytypes (6H-PSiC with inclusions of 15R- and 4H-PSiC).",
