Tb doped carbon dots as a platform for fluorescence ratiometric and colorimetric sensor for deferasirox

Characterization of Tb-CDs

Tb-CDs were prepared by a simple hydrothermal method from Tb(NO₃)₃ and folic acid as sources of Tb and C. TEM imaging (Fig. 1a) indicated the nanoparticles with sizes smaller than 10 nm²¹. In the presence of Tb(NO₃)₃,…
