Techniques for generating quantum light emitters that operate at room temperature and at telecom wavelengths are described. Quantum light emitters of the present disclosure may have various structures. For examples, an SWCNT may chirality of (6,5), (7,5), or (10,3). Quantum light emitters of the present disclosure may be doped with various compounds. In at least some examples, an SWCNT may be doped with an aryl dopant. In at least some examples, the aryl dopant may be an aryl diazonium dopant. Example aryl diazonium dopants include, but are not limited to, 3,5-dichlorobenzenediazonium (Cl2-Dz) and 4-methoxybenzenediazonium (MeO-Dz). Quantum light emitters of the present disclosure may be encapsulated in various materials. In at least some examples, an SWCNT may be encapsulated in a surfactant. An example surfactant is sodium deoxycholate (DOC). In at least some other examples, an SWCNT may be encapsulated in a polymer. In at least some examples, the polymer may be a polyfluorene polymer. An example polyfluorene polymer is a copolymer of 9,9-dioctylfluorenyl-2,7-diyl and bipyridine (PFO-BPy).
