Abstract
Photo-luminescent dye, 1-(2-amino-phenyl) naphthalene-2-ylamine (APNA) molecules were synthesized and encapsulated inside single-walled carbon nanotubes (APNA@SWNTs) in vacuum. Here we measured X-ray diffraction (XRD) pattern and attenuated total reflectance (ATR) spectrum to confirm the encapsulation of APNA molecules inside SWNTs. Strong photoluminescence (PL) spectrum was observed around 400 nm at an excitation of 326 nm. We employed the PL intensity of the dye to reveal suspension stability of SWNTs in solvents. The intensity of PL spectrum increased as a function of SWNTs suspension stability, i.e., the PL intensity was proportional to suspension stability of SWNTs in various solvents.
