Upconversion Luminescence of Silica–Calcia Nanoparticles Co-doped with Tm<sup>3+</sup> and Yb<sup>3+</sup> Ions
Looking for upconverting biocompatible nanoparticles, we have prepared by the sol–gel method, silica–calcia glass nanopowders doped with different concentration of Tm<sup>3+</sup> and Yb<sup>3+</sup> ions (Tm<sup>3+</sup> from 0.15 mol% up to 0.5 mol% and Yb<su...
