Abstract

The structural and morphological characterizations of the NaYF4 nanostructured glass ceramic with different concentrations of Er3+ are characterized. The red and green up conversion emission of different sa mples are measured, respectively. With the increase of the Er 3+ doping concentration, the green emission intensity first increases, and then decreases, while the red emission intensity continuously rises. Besides, combined with the ratio of the green emiss ion to the red emission and the energy diagram of Er3+ ions, the luminescent mechanism of the tunable red green luminescence is explained. Finally, it’s proved that the concentration quenching of green emission is close to an electric dipole-dipole interaction..
