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.
Journal for Nanoscience and Nanotechnology (JNN) is an international and multidisciplinary peer-reviewed journal with a wide-ranging coverage, consolidating research activities in all areas of nanoscience and nanotechnology into a single and unique reference source. JNN is the first cross-disciplinary journal to publish original full research articles, rapid communications of important new scientific and technological findings, timely state-of-the-art reviews with author's photo and short biography, and current research news encompassing the fundamental and applied research in all disciplines of science, engineering and medicine.
