Description

<p>Near-infrared photoluminescence of single-walled carbon nanotubes is expected to be used for light emitting materials in optical communication light sources and bioimaging. For their practical applications, it is an important issue to improve their low PL quantum yields. Recently, local band-structure modulation has been achieved by appropriate chemical derivatization to allow bright new-red shifted PL peaks to emerge. Interestingly, it has been revealed that the PL wavelength and intensity are tunable depending on the chemical reaction, the structure of the reagents used, and the degree of functionalization of the carbon nanotubes. The chemical functionalization of carbon nanotubes is highly desirable owing to its applicability in various NIR PL applications.</p>
