Data from Hunan University Provide New Insights into Materials Science (The study on crystal defects-involved energy transfer process of Eu3+ doped ZnO lattice)

By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Materials Science are presented in a new report. According to news reporting out of Changsha, People's Republic of China, by VerticalNews editors, research stated, "Eu3+ doped ZnO nanoparticles are synthesized by solvothermal reaction and following annealing process. When molar ratio of Eu/Zn is increased from 0.01 to 0.03, a small percentage of Eu3+ is slowly separated from host ZnO lattice accompanied by decrease of average particle size."

Our news journalists obtained a quote from the research from Hunan University, "However, the proportion of individual Eu2O3 particles in doped ZnO is extremely low. After doping, a great deal of crystal defects are generated in host ZnO lattice, in which O vacancy, interstitial Zn and interstitial O are involved in energy transfer from host lattice to Eu3+."

According to the news editors, the research concluded: "Among them interstitial O plays an important bridge role in this process."
