Controllable Synthesis of Monodisperse CaF2 microsphere and the investigation on luminous performance of CaF2:Ce3+/Tb3+

, , , , , , , , , , , , ,
Highly uniform and well-dispersed CaF2 microsphere and hollow spheres with tunable particles size (100nm-900nm) have been successfully synthesized by a facile hydrothermal process using ethylenediaminetetraacetic acid disodium as a complexing reagent. The XRD results indicated [...]

Time-Resolved Luminescence Measurements on Up-Conversion Phosphors for Electron Beam Sterilization Monitoring

, , , , , , , ,
We present recent investigations on time-resolved measurements on alterations in the temporal luminescence decay of up-conversion phosphors induced by electron beam treatment. As a consequence of the tight regulations concerning sterility in the food and [...]
