Synthesis and photoluminescence of Eu-doped ZnO microrods prepared by hydrothermal method

The Effect of Synthesis Pressure on Properties of Eu-Doped ZnO Nanopowders Prepared by Microwave Hydrothermal Method

“…The Eu 3+ ions occupy the lattice sites of Zn 2+ causing the increase in the inter-atomic distance and thus leading to the change in lattice parameters. A similar phenomenon was observed in other studies on Eu-doped ZnO structures [17,18]. However, diffraction peaks from impurities are found in all the samples.…”

Dependence of energy transfer and photoluminescence on tailored defects in Eu-doped ZnO nanosheets-based microflowers

“…In a recent work, Zeng et al claimed that Eu 2+ ions act as trapping centers in Eu-doped ZnO microflowers and transfer energy to the Eu 3+ ions [19], consequently leading to red emission. Wang et al indicated that the surface defects may dedicate the process of energy transfer from ZnO to Eu 3+ ions [20]. However, there have been no systematic studies on defects engineering upon the energy transfer efficiency in Eu-doped ZnO system.…”

Microstructure and Luminescence Properties of Tb3+ Doped ZnO Quantum Dots

“…There are various methods to synthesize ZnO QDs, such as thermal deposition, 9 thermal evaporation, 10 ion implantation, 11 sputtering, 12 solgel method, 13 14 and hydrothermal method. 6 In this study, sol-gel method was used to fabricate ZnO QDs since it has many advantages, such as simple processes and high homogeneity in distribution of the doping ions within the host.
