Abstract
Lanthanide-activated upconversion (UC) materials are fascinating for the new generation of biomedicine, because its unique ability to transform near-infrared light into visible light. Based on it, a set of fluoroindate glass matrices co-doped with Yb3+ and Tm3+ were prepared using the melting quenching technique. Then, the sample with the highest blue upconverted emission was milled and functionalized with chitosan (CS). The blue UC emission spectra of the glass increase with increasing Yb3+ concentration up to 1.8 mol%, then decreased. This could be attributed to the mechanism involved in the UC process, as confirmed by power dependence assessment. Also, according with the decay times the energy transfer efficacy of the samples is ∼50%. The milling of the glass resulted in particles of 44.8 ± 7.7 nm, which were successfully functionalized with CS. The CS-coated particles showed good cell viability, indicating that they could potentially be used in some biomedical applications.
