Abstract:

In the nanocomplexes with Yb³⁺, Er³⁺-codoped calcium fluoride (CaF₂:Yb³⁺, Er³⁺) nanoparticles, the infrared (IR)-to-ultraviolet (UV) upconversion (UC) properties were explored under 980 nm laser diode (LD) excitation. The strong enhancement of UV emission at 407 nm was observed. An UP mechanism of the materials was discussed.
