  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.
