Abstract
We measured the absorption/transmission performance of ZnO thin films doped with europium (Eu) and aluminum (Al). ZnO and Zn1−(y+0.01)(Al0.01, Euy)O (y = 0.00, 0.01, 0.03 and 0.05) nano particles were synthesized using sol–gel method and covered on a soda-lime glass surface by spin coating. After annealing at 500 °C, UV–Vis. measurements were performed in wavelength range of 300 and 800 nm to calculate the band gap of nano particles from the absorption/transmission performances. The resistivity measurements were employed to understand the relationship between band gap and DC electrical performance by Eu amount of each Zn1−(y+0.01)(Al0.01, Eu y )O thin film. As a conclusion, after reaching a minimum value with 1 mol% Eu doping, a monotonic increase in band gap was observed by enhancing Eu amounts in Zn0.99Al0.01O lattice.
