Abstract

Objective (s): This paper describes synthesis Polyvinyl Alcohol/CaF2: Er NANOFIBERS because of its PHOTOLUMINESCENCE properties.Materials and Methods: First, CaF2: Er NANOCOMPOSITE synthesized with co-precipitation method. In order to prepare polyvinyl alcohol (PVA)/CaF2: Er NANOFIBERS, CaF2: Er NANOCOMPOSITEs were added to the polyvinyl alcohol (PVA) polymer. PVA/CaF2: Er composite NANOFIBERS were successfully prepared by electrospinning technique.Results: X-Ray Diffraction (XRD) pattern and Transmission Electron Microscopy (TEM) images indicate that the CaF2: Er NANOCOMPOSITE was formed with cubic phase and the average crystalline size was calculated using the Scherrer's equation is about 26-28 nm. Scanning Electron Microscopy (SEM) images show that the diameters of the fine NANOFIBERS are in the range of 60-110 nm. For studying luminescence properties of the NANOFIBERS, the samples excited with different wavelengths and show excellent UP-CONVERSION luminescence transition.Conclusion: PHOTOLUMINESCENCE spectrums of the PVA/CaF2: Er NANOFIBERS illustrate UP-CONVERSION luminescence process. This unique property can have high potential for laser application and bio-imaging in medical technology.
