Optical Spectroscopy of Transition Metal Doped ZnO Nanoparticles.
Dr. Dmitri Tenne
Transition metal doped oxides have a wide range of potential applications, from microelectronics and optielectronics to novel cancer treatments. We have investigated ZnO nanoparticles doped with transition metals (Cr, Mn, Fe, Co, Ni) over a range of increasing percentages from 0 to 10 percent by photoluminescence and Raman spectroscopy. All samples were synthesized via a forced hydrolysis method. The effect of composition and type of dopant on optical emission and vibrational spectra of the nanoparticles has been studied.
