Abstract: Microresonators (MRs) comprising spherical particles of amorphous silicon dioxide with diameters of 2.0 and 3.5 $\mu$m coated with a 60-nm-thickness luminescent coat of amorphous hydrogenated silicon carbide ($a$-Si: C: H) were produced. Enhancement and modification of the continuous wide photoluminescence spectrum of the $a$-Si: C: H in the visible-near-infrared region at room temperature into a line spectrum displaying intense narrow bands with positions coinciding with the whispering-gallery modes of spherical MRs were demonstrated.
