ZnO:Mg thin film had been synthesized by sol-gel spin coating method. The materials used were zinc acetate dehydrate, magnesium, isoprol as a solution and diethanolamine as stabilizer. Concentration variation between Mg doped ZnO were 0.5; 1.0; 1.5; 2.0 and 2.5%. The XRD results showed that all samples were wurtize hexagonal with the smallest size of 24 nm for Mg doped of 0.5% and the biggest size of 28 nm for Mg doped of 2.5%. The SEM results showed that the ZnO:Mg thin film morphology was uniform round granules. The UV-Vis results showed the biggest transmission and absorbance values were in the range of 310 - 420 nm, and band gap of 3.155 - 3.217 eV.
