Abstract: Photoluminescence properties of semiconducting single wall carbon nanotubess-SWNT thin films with different metallic single wall carbon nanotubesm-SWNT concentrations are reported. s-SWNT purified samples are obtained bypolymer assisted selective extraction. We show that a few m-SWNT in the samplegenerates a drastic quenching of the emission. Therefore, highly purifieds-SWNT films are a strongly luminescent material and a good candidate forfuture applications in photonics, such as near infrared emitters, modulatorsand detectors.
