Temperature self-monitoring photothermal nano-particles of Er3+/Yb3+ Co-doped zircon-tetragonal BiVO4

Jiashu Sun et al.

Summary: This study developed spindle-like zircon-tetragonal (z-t) phase BiVO4:Yb3+/Er3+ up-conversion (UC) nano-particles as self-monitored photo-thermal therapeutic agents. By monitoring the thermo-responsive emission intensity ratio of Er3+, real-time thermometry was achieved under 980 nm laser diode excitation. The optimal sample composition was determined to be BiVO4:20%Yb3+/3%Er3+, showcasing high sensitivity and efficiency in temperature monitoring and photo-thermal conversion.

Enhancing upconversion luminescence and thermal sensing properties of Er/Yb co-doped oxysulfide core-shell nanocrystals

Jianxin Jiao et al.

Summary: The study explores the upconversion luminescence and thermal sensing properties of Er3+, Yb(3+)co-doped oxysulfide, demonstrating that constructing an active shell with an optimum concentration of sensitizers is an efficient way to enhance luminescent intensities and thermal sensitivity. Increasing the Yb(3+)concentration in the shell activates new quenching pathways of Er3+ -> Yb3+ -> quencher from the core to the shell, impacting luminescent intensity. Overall, this research provides a feasible and versatile method to improve the luminescence and thermal sensing properties of Ln(3+)-based materials.
