(Invited) Lanthanides Fluorides Doped Nanocrystals for Biomedical Applications
In this work, we will present optical (photoluminescence (PL), PL excitation, PL decay, FTIR, Raman) and structural (XRD, HR-TEM) results obtained for NaYF4 and NaGdF4 nanocrystals doped with Eu, Er, Tm and Yb ions. Based on obtained results, we will discuss examples of ion-ion interaction like: cross-relaxation, energy migration or up-conversion [1, 2] and influence of these interactions on resultant emission properties of RENCs. Additionally, we will discuss the effect of the nanocrystals surface and their core-shell geometry on the excitation and emission properties of lanthanides in RENCs [1, 3]. Finally, we will discuss a few examples of potential application of RENCs in bio-medicine.
