We have produced new types of carbonaceous condensates from the ejecta of a hydrocarbon plasma. These condensates are named Quenched Carbonaceous Composites (QCC). There are various types of QCC formed around the center of the ejecta that show an absorption feature in the spectral range 220-250nm. The QCC with an absorption feature at 220nm is composed of onion-like spherules; that with an absorption feature at 230-240nm are composed of polyhedral particles; and that with an absorption feature at 250nm is composed of ribbons with bent graphitic layers. The 240-250nm absorption feature of the hot evolved star V348Sgr can be matched by the ribbon-like QCC, suggesting that this type of QCC may be present in the circumstellar shell of this star.
