- 01HK7X3RR817R88TYDM07PWA03 abstract "The quest for highly efficient upconversion (UC) materials has led to the development of fluoride hosts with low phonon energies, minimizing nonradiative transitions. Among them, NaYF4 doped with Yb3+ and Er3+ has emerged as a top performer. However, its limited thermal stability hinders its application in certain fields. On the other hand, oxide hosts offer improved stability but suffer from lower UC efficiencies due to higher phonon energies. Hence, the prospect of developing host materials that combine the robustness of oxides with the high upconversion efficiencies of fluorides remains an intriguing avenue of exploration. Herein, we present a novel approach wherein we successfully synthesize lanthanide-doped oxyfluoride particles. This is achieved through the growth of a NaYF4:Yb3+,Er3+ layer around SiO2 spherical particles, followed by a high-temperature annealing process, yielding SiO2@YOF:Yb3+,Er3+ particles. Our primary focus was to exploit these materials as Boltzmann type luminescence thermometers within the physiological range. Nonetheless, we encounter a noteworthy challenge concerning the limited emission observed in the green spectral region of these particles. To address this limitation, we have investigated the effects of introducing various metal ion co-dopants (Gd3+, Li+, or Mn2+) into the SiO2@YOF:Yb3+,Er3+ particles. Specifically, we analyze the overall emission intensity and the green to red ratio under 975 nm laser excitation. Beyond their role as ratiometric thermometers, our investigation uncovers the remarkable potential of these materials as carriers for drug delivery applications, following the conversion of SiO2@YOF:Yb3+,Er3+ particles into hollow YOF:Yb3+,Er3+ structures, and their evaluation in terms of toxicity towards NHDFs. The investigation highlights the previously unexplored aspects of improving the green upconversion luminescence in YOF:Yb3+,Er3+ and its potential biomedical applications.".
