摘 要: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.
