The synthesized Eu 3+ / Cu 2+ doped ZrO2 nanoparticles were observed to have sphere morphology with a diameter of ~ 25 nm. The XRD patterns of the nanoparticles revealed the peaks that were to be crystalline tetragonal ZrO2. The addition of Cu 2+ to the Eu 3+ doped ZrO2 nanoparticles resulted in a significant suppress luminescence in Eu 3+ / Cu 2+ doped ZrO2 nanoparticles, which was attributed to the spectral overlap occurs between Cu 2+ absorption and Eu 3+ emission (5D0→ 7F2 transition).
