Luminescent materials based on lanthanide doped bismuth oxyfluoride particles for nanophosphor and nanothermometer applications

Abstract

The project is focus on the synthesis and characterization of lanthanide bismuth oxyfluoride particles. The samples are synthesized through homogeneous precipitation using a microwave reactor to heat. Furthermore, by doping with different lanthanides (Tb, Eu, Tb-Eu; Pr; Nd; Yb-Ln, Ln=Er,Yb,Tm) it is tested how the optical response of the systems can be in terms of luminescence spectroscopy. The synthesized Ln3+ NPs are tested for the biological applications as nanothermometer. In recent times Luminescent nanothermometers have been widely investigated because they relate the local temperature of a biological system with their emission, as a result of an external radiation. Through these systems there is the possibility of excitation and / or emission in the so-called first and second biological window. The studies of these project are focused on NPs doped Ln3+ as thermal and emitting probes.
