Abstract:Rare
earth ion doped upconverison (UC) luminescence nanophosphors
have attracted much attention owing to their wide applications. It
is known that homogeneous doping of ions in matrixes and particle
size distribution (PSD) determine the luminescent properties. In this
study, we reported a novel approach to prepare CaF2:Er3+ and CaF2:Yb3+/Er3+ UC nanophosphors
by high-gravity reactive precipitation in a rotating packed bed (RPB)
combining hydrothermal process, which is applied for noninvasive temperature
