Article Synopsis
- * Adding Ag nanoparticles significantly boosts the up-conversion emission at specific wavelengths, reaching a maximum enhancement factor of about 15.6 at 476 nm.
- * The research further explores the use of microfibers made from these nanomaterials as waveguides, revealing that those with Ag nanoparticles show greater temperature sensitivity, suggesting potential applications in creating new nano-thermometers for biological and industrial use.

This paper reports the synthesis of a β-NaYF:Yb/Tm phosphor by a thermal decomposition method and focuses on the fabrication of microfibers by the co-doping of nanocrystals with PMMA solution a facile drawing method. The structural characteristics of the nanocrystals are studied by XRD and TEM techniques. Meanwhile, the optical properties of the microfibers are probed by wave guiding performance and upconversion spectroscopy.
