Nano technology is burgeoning interdisciplinary area of research in variety of fields, has the potential to enable breakthrough application in agriculture regarding plant protection and nutrition. This study aimed to preparation of magnesium oxide nano particles and study of the optical properties using UV spectrometer. In this study five samples different molar proportion of magnesium hydroxide were used to study the optical properties. Glass cylinders were used and cleaned with alcohol and distilled water. At a temperature of 80℃ Celsius for an hour with a magnetic mixer, the solution was left for a period of 24 hours at room temperature, then entered to oven (Microwave) at a temperature of 300℃ Celsius for a period of 3 hours, and that obtain the magnesium oxide with different morality (0.1, 0.3, 0.5, 0.7, and 0.9). The absorption value, the absorption coefficient value (α), the excitation coefficient value (K), the optical energy band gap value (Eg), and the refractive index (n) were calculated using UV Ultra VioletVisible. The results were as follows by order: (0.2×109 , 0.4×105 , 0.6×106 , 0.8×104 , 1.0×10 cm-1 ), (9.0×103 , 1.88×104 , 2.82×104 , 3.76×104, 4.70 ×104), (2.50×10-2 , 5.55×10-2 , 7.50×10-2 , 1.00×10-1 , 1.25×10-1 ), (3.282 , 3.238 , 3.195 , 3.152 , 3.121 ,( ev.cm-1)-2),(0.28 , 0.56 , 0.84 , 1.12 , 1.40) respectively. having the same wavelength, so the absorption, the absorption coefficient (α), the excitation coefficient (K), the energy band gap(Eg), and the refractive index(n) increased with increasing wavelength. Magnesium oxide cannot be present alone in nature because it has a relatively high chemical activity Therefore it is necessary to make alloys and can not be kept as powder in normal stores. This study recommends that preparing samples of magnesium oxide by film and study some electrical properties of these samples with different thicknesses.
