(a) X-ray diffraction (XRD) patterns of NaYF4:Yb/Tm (top) and NaYF4:Yb/Tm@NaGdF4 (bottom). (b) Energy-dispersive X-ray (EDX) spectra of NaYF4:Yb/Tm and NaYF4:Yb/Tm@NaGdF4. (c) Dynamic light scattering (DLS) sizes (intensity-based) (left) and zeta potentials (right) of oleic acid-free UCNP, PEG-UCNP, and ANG-PEG-UCNP, respectively. (d)T1-weighted magnetic resonance images of ANG-PEG-UCNP with different Gd3+ concentrations and R1 plots against Gd3 + concentrations
