Preparation of the BaF2: Ce3+, Yb3+ Nanoparticles and near Infrared Luminescent Properties

Article Preview

Abstract:

The BaF2: Ce3+, Yb3+ nanoparticles doped with different concentration were prepared by a hydrothermal method. The structure,morphology and photoluminescence properties were studied. In BaF2: Ce3+, Yb3+ nanoparticles, a strong near infrared emissionat 900 – 1050 nm matching to energy of Si band gap of Si-based solar cells was observed under the excitation of 5d level of Ce3+. As a downconversion luminescent convertor, the kinds of materials have potential to be applied in front of Si-based solar cells to reduce thermalization loss and enhance conversion efficiency of solar cells.
