چکیده انگلیسی
In present work, the pure and europium (Eu) incorporated zinc oxide (ZnO) thin films were deposited with sol-gel spin coating by using zinc acetate dehydrate and Eu (III) chloride salts. The coated films were examined by means of XRD, AFM and UV/VIS spectrophotometer. The ZnO hexagonal wurtzite nanoparticles with (002) preferential direction were observed for all films. The values of crystallite size, micro-strain and surface roughness continuously increased from 21Â nm, 1.10Â ÃÂ 10â3 and 2.43Â nm to the values of 35.56Â nm, 1.98Â ÃÂ 10â3 and 28.99Â nm with Eu doping, respectively. The optical band gap value of the pure ZnO initially increased from 3.296Â eV to 3.328Â eV with Eu doping up to 2Â at.% doping level, then it started to decrease with more Eu content. The electrical features of Al/n-ZnO:Eu/p-Si heterojunction diodes were inquired by current-voltage (I-V) measurements at the room temperature.
