| dc.description.abstract | The nanoparticles of NaYF4: Er3+, Yb3+, Nd3+ present fluorescent emissions by upconversion. These emissions are associated with the doping ions of Er, Yb and Nd in the NaYF4 nanoparticles. The nanoparticles of NaYF4 doped with Er3+ and Yb3+ ions produce upconversion radiation when excited by 980 nm wavelength laser. By incorporating the Nd3+ ions, the NaYF4: Er3+, Yb3+, Nd3+ arrangement is formed, which produces the same excitation with an 880 nm wavelength laser, the product of a cross-transfer process between the Nd, the Yb and the Er. For applications in human tissue it is preferable to use a 880 nm wavelength laser. These nanoparticles of NaYF4: Er3+, Yb3+, Nd3+ have been synthesized in our laboratories with Y (79,3%), Yb (18%), Er (2%) and Nd (0,7%). In this work we have studied the fluorescence behavior of these nanoparticles, which correspond to the transitions 2H11/2 → 4I15/2 y4S3/2 → 4I15/2, and that can be used in the calibration of a remote nanothermometer, because they have a sensitivity to very small changes in temperature. | |
