Optical properties of quantum-dot-decorated polymer nanofibers. Nanotechnology, 2011, vol. 22, No. 33, 335202
We report a one-step process for decorating poly(trimethylene terephthalate) (PTT) nanofibers
with CdSe/ZnS core/shell quantum dots (QDs). Using the QD-decorated PTT nanofibers with
diameters of 400–800 nm as active subwavelength waveguides, their high photostability for
630 nm red light and low absorption coefficient down to 2.6 cm−1 were characterized by both
evanescent waveguiding excitation and irradiation excitation. Compared with the irradiation
excitation, a 200 times enhancement was obtained from the active subwavelength waveguides
under the evanescent waveguiding excitation.
