We present the photoluminescent properties of trions trapped within the quantum well originated by the formation of sp3 defect via organic molecule functionalization in semiconducting single walled carbon nanotube (SWCNT). Trion is the three-body charged exciton, bound state which offers unique properties by manipulating charge, spin, and excitation in one dimensional SWCNT. We employed a model of periodic nanotube covalently functionalized with aryl molecule incorporating sp3 defect using the PBE and B3LYP exchange functionals within the plane wave basis sets. We predicted the trions in excited states are optically active than the excitons with more red-shifted lowest lying transition emitting single photon within the wavelength of optical communication band (1500-2000 nm). Our findings open possibilities for exploiting trions of SWCNT in optoelectronics, ranging from photovoltaics, bio-imaging, telecommunication, and quantum technology.
