By a News Reporter-Staff News Editor at Electronics Newsweekly -- Investigators publish new report on Superconductivity. According to news originating from Queretaro, Mexico, by VerticalNews correspondents, research stated, "In this study, thin films of molybdenum oxide were prepared by spray pyrolysis technique on glass substrates. The influence of substrate temperature on their crystallographic structure, surface morphology, and optical properties was studied."
Our news journalists obtained a quote from the research from National Autonomous University, "The formation of a MoO3 film on the substrate was confirmed through XRD analysis. Furthermore, the presence of the two phases alpha and beta in each of the films was evident. The percentage of phase alpha varied from 55 % for the film deposited at 200 degrees C up to 97 % for the film deposited at 400 degrees C. According to SEM images, MoO3 films have a sponge-type structure on the order of nanometers. Both the optical gap and the refraction index strongly depend on substrate temperature."
According to the news editors, the research concluded: "The optical gap decreases from 3.63 eV for the film deposited at 150 degrees C up to 3.30 eV for the one prepared at 400 degrees C. On the contrary, the refraction index measured at 800 nm increases from 1.54 up to 1.61 for the films prepared at 150 degrees C and 400 degrees C, respectively."
