Looking for upconverting biocompatible nanoparticles, we have prepared by the sol–gel
method, silica–calcia glass nanopowders doped with different concentration of Tm3+ and …

A series of rare earth ions (Eu 3+, Sm 3+, Yb 3+/Er 3+, Yb 3+/Ho 3+, Yb 3+/Tm 3+) doped
bismuth molybdate (Bi 2 MoO 6) phosphors with excellent multicolor luminescence have …

The establishment of structural-properties relationships in glass containing modified rare
earth in magnesium borotellurite (BTM) with manganese nanoparticles remains a challenge …

Global transitions to low-carbon energy systems are heavily reliant on the large-scale
extraction of critical minerals (eg cobalt, lithium, rare earth elements). These minerals are …

A process aimed at the recovery of terbium from liquid solutions using activated carbon (AC)
derived from spent coffee grounds (SCG) was assessed. AC was obtained using the hydro …
