The Role of Cu 2+ Concentration in Luminescence Quenching of Eu 3+ / Cu 2+ Co-doped ZrO2 Nanoparticles
This paper the role of Cu 2+ concentrations in luminescence quenching of Eu 3+ / Cu 2+ doped ZrO2 nanoparticles synthesized by co-precipitation method. 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 n...

| 總結: | This paper the role of Cu 2+ concentrations in luminescence quenching of Eu 3+ / Cu 2+ doped ZrO2 nanoparticles synthesized by co-precipitation method. 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). |
