Dx. Ouyang et al., RELATIONSHIP BETWEEN OPTICAL TRANSMITTANCE AND MICROSTRUCTURE OF NANOSTRUCTURED ALUMINA FILMS, Nanostructured materials, 7(5), 1996, pp. 573-578
Nanostructured boehmite and Al2O3 films were prepared by the sol-gel r
oute. Microstructural features, such as phase content, grain orientati
on and grain diameter, were observed. The relationship between the tra
nsmittance in the visible to near infrared range and the film microstr
ucture is discussed.
