摘要：

Nanostructured manganese oxide (Mn2O3) thin films were synthesized by spin coating method. The effect of preparation conditions, such as calcination temperature, rotation speed, as well as solution aging time on structural, morphological, and optical properties of the samples were investigated. The phase of the grown films changed from amorphous to orthorhombic by applying the calcination temperature beyond 400 degrees C. At low calcination temperature, agglomerations of the particles happened and no uniform structure formed. Furthermore, the results indicated that employing higher rotation speeds led to decrement of the samples crystallinity. Aging the solution did not change the absorption edge of the samples. However, the optical transmittance of the samples decreased by about 10 percent. Surface FESEM image of seven layer Mn2O3 thin film calcined at 500 degrees C [GRAPHICS] .
