Study structural and up-conversion luminescence properties of polyvinyl alcohol/CaF2:erbium nanofibers for potential medical applications
Objective(s): This paper describes synthesisPolyvinyl 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...
متن کاملCombustion synthesis and up-conversion luminescence of La2O2S:Er3+,Yb3+ nanophosphors
La2O2S:Er ,Yb nanocrystalline up-converting phosphors were synthesized by a combustion method at low temperature, using ethanol as pre-ignition fuel and thioacetamide as sulfurizing agent and organic fuel. The phosphors were characterized by powder X-ray diffractometry, scanning electron microscopy, UV/Vis/NIR spectroscopy and fluorescence spectroscopy. Pure and well-crystallized La2O2S:Er ,Yb ...

متن کاملUp-conversion luminescence of Mn2+ ions in Zn1−xMgxS:Mn nanoparticles
The up-conversion luminescence of Zn1−xMgxS:Mn 2+ nanoparticles fabricated by an inorganic precipitation method is studied by using a near-infrared femtosecond laser. The up-converted luminescence is blueshifted when increasing the Mg composition because of weaker crystal field effect. Comparing with thin films, the luminescence of Zn1−xMgxS:Mn 2+ nanoparticles shifts several nanometers to the ...

Consider two adolescents: Person One and Person Two. Person One has never used substances and exhibits relatively few behavioral (conduct) problems. On the other hand, Person Two uses substances frequently and more commonly exhibits poor conduct. If you were to guess, which of the individuals would you expect to have lower overall judgment and self-regulation? If you answered Person Two, your i...
