Abstract

Er³⁺-Yb³⁺ co-doped KGd₃F₁₀ cores, prepared by an ethylenediaminetetraacetic acid (EDTA)-assisted hydrothermal synthesis, and core-shell Er³⁺-Yb³⁺ KGd₃F₁₀@SiO₂ particles, prepared through Stöber method have been morphologically and optically characterized. Besides being employed in nanothermometry, both core and core-shell have also been exploited as contrast agents for photoacoustic images (PAI). Results of PAI upon excitation at 520 nm and 980 nm in the Er³⁺-Yb³⁺ core and core-shell nanoparticles in ethanol suspension are demonstrated and its biomedical applications discussed.
