Highly efficient green up-conversion emission from fluoroindate glass nanoparticles functionalized with a biocompatible polymer.

ABSTRACT: Up-conversion nanoparticles have garnered lots of attention due to their ability to transform low energy light (near-infrared) into high-energy (visible) light, enabling their potential use as remote visible light nano-transducers. However, their low efficiency restricts their full potential. To overcome this disadvantage, fluoroindate glasses (InF₃) doped at different molar concentrations of Yb³⁺ and Er³⁺ were obtained using the melting-quenching technique, reaching the highest green emission at 1.4Yb and 1.75Er (mol%), which corresponds to the ⁴S_3/2 → ⁴I_15/2 (540-552 nm) transition. The particles possess the amorphous nature of the glass and have a high thermostability, as corroborated by thermogravimetric assay
