Based on thorough Rayleigh scattering, Raman scattering, and PL experiments, we are able to demonstrate that the ISCT PL is observed with a quantum yield estimated to be a few 10-6 independent of the semiconducting or metallic nature of the outer tube. This result is mainly attributed to ultrafast exciton transfer from the inner to outer tube. Furthermore, by carrying out PL excitation experiments on the (14, 1)@(15, 12) DWNT, we show that the ISCT PL can be detected through the optical excitation of the outer tube, indicating that the exciton transfer can also occur in the opposite way. 000065254 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/MAT2016-79776-P$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 642742-Enabling Excellence$$9info:eu-repo/grantAgreement/EC/H2020/642742/EU/Graphene-based nanomaterials for touchscreen technologies: Comprehension, Commerce and Communication/Enabling Excellence 000065254 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc$$uhttp://creativecommons.org/licenses/by-nc/3.0/es/ 000065254 590__ $$a3.813$$b2017 000065254 591__ $$aPHYSICS, CONDENSED MATTER$$b18 / 67 = 0.269$$c2017$$dQ2$$eT1 000065254 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000065254 700__ $$aParret, R. 000065254 700__ $$aTran, H.-N. 000065254 700__ $$aMichel, T. 000065254 700__ $$aCao, T.T. 000065254 700__ $$aNguyen, V.C. 000065254 700__ $$0(orcid)0000-0002-2071-9093$$aArenal, R.$$uUniversidad de Zaragoza 000065254 700__ $$aPopov, V.N. 000065254 700__ $$aRochal, S.B. 000065254 700__ $$aSauvajol, J.-L. 000065254 700__ $$aZahab, A.-A. 000065254 700__ $$aPaillet, M. 000065254 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
