Abstract

Zirconium metal–organic frameworks ZrOBDC (where BDC = C6H4(COOH)2, terephthalic acid) doped and co-doped with rare earth ions Ln (ZrOBDC:Ln3+, where Ln3+ = Eu3+ and Tb3+ as well as Er3+ and Yb3+) were used as precursors for the design of tetragonal rare earth doped zirconia nanoparticles (t-ZrO2:Ln3+ NPs) through annealing process. Preparation, characterization and luminescence properties of ZrOBDC:Ln3+ and ZrO2:Ln3+ NPs were investigated. The as-obtained t-ZrO2:Ln3+ NPs have high purity with an average size of 20–30 nm. The luminescence spectra of ZrOBDC:Tb3+ and ZrOBDC:Eu3+ display strong green and red emission at around 544 and 611 nm which correspond to 5D4 → 7F5 and 5D0 → 7F2 transitions of Tb3+ and Eu3+ ions, respectively. The green and red up-conversion emissions of ZrO2:Er3+,Yb3+ NPs due to 2H11/2, 4S3/2 → 4I15/2 and 4F9/2 → 4I15/2 transitions of the Er3+ ions are observed under 976 nm laser excitation.
