Modification on upconversion luminescence of Er3+-Yb3+ co-doped BiOCl semiconductor nanosheets through interaction between nanohost and doping lanthanide.

We reported the upconversion luminescence (UCL) properties of Er3+-Yb3+ co-doped BiOCl semiconductor nanosheets synthesized by hydrothermal method. Under 980nm excitation, the red and green UCL of Er3+ ions were observed to be populated by a four and three-photon process in the case of absent or low concentration Yb3+ dopant. However, an increase of Yb3… CONTINUE READING
