Abstract:
We report the successful fabrication of (Er 3+ , Yb 3+ )-co-doped ZnO transparent hybrid materials by controlling compositions and crystallization. The singly precipitated ZnO nanocrystals were preferentially oriented along the c -axis on the glass surface, leading to an intense luminescence at the bandgap energy of ZnO. The Er 3+ and Yb 3+ ions assembled around the low-phonon-energy ZnO nanocrystals, achieving an enhanced two-photon upconversion emission in the visible region. In addition, the glass ceramic exhibited typical paramagnetism with antiferromagnetic interactions. The multifunctional combination in such a low-cost, easily shapable and environmentally friendly bulk material may find a wide range of device applications.
