摘要: CdTe quantum dot/PVA (poly vinyl alcohol) composite nanofiber was successfully fabricated by eletrospinning process. dots were uniformly dispersed and stabilized into solid structure. Spectrofluorometer analysis revealed whenever Q.D’s enter to the PVA solution, due aggregation of red shift happens; however, when blend Q.D-PVA solution changes form via electrospining, this phenomenon offsets original fluorescence properties does not degraded excellent individual dispersion Q.D in nanofibers It is also turned out that proportion incorporated electrospining has strong influence on morphology. Addition causes remarkable conductivity viscosity, therefore different morphologies can be obtained as evidenced scanning electron microscopy. Furthermore, differential calorimetric (DSC) addition small amount strenuous improvement crystalinity heat fusion. Fluorescence transmission microscopy (TEM) measurements confirmed evenly structures.
