- Аннотация: Molecules encapsulation inside the single-walled carbon nanotube (SWCNT) core has been demonstrated as a successful route for modification of nanotube properties. SWCNT diameter-dependent filling results in the band gap modification together with the enhancement of photoluminescence quantum yield. However, interaction between the inner structure and the outer shell becomes complex. It depends on the molecules orientation inside, geometry of the host nanotube and on several rival mechanisms determining the resulting properties of the hybrid nanosystem. In this work we study the influence of encapsulated graphene nanoribbons on the optical properties of host single-walled carbon nanotubes. The interplay of strain and dielectric screening caused by the internal environment of the nanotube affects its band gap. The photoluminescence of the filled nanotubes becomes enhanced when the graphene nanoribbons are polymerized inside the SWCNTs at low temperatures. We show the gradual photoluminescence quenching together with the selective signal enhancement for the exact nanotube geometries, specifically (14,6) and (13,8) species. A precise adjustment of the optical properties and the enhancement of the photoluminescence quantum yield upon filling for nanotube with specific diameters were assigned to the optimal organization of inner structures.
