“…The intensity ratio of metal oxide to metal ions has previously been applied to estimate oxygen coverage on metal surfaces. 36 Figure 7 shows the variation of intensity ratio of ZnO þ to Zn þ with respect to bombarding time for different ZnO/Al nanostructures. As expected, ZnO þ /Zn þ ratio for the three samples increases with growth time indicating the presence of higher ZnO phase in the nanostructures grown in higher reaction time.…”

We report on the visible light induced photocatalytic responses of zinc oxide (ZnO) nanostructures in the form of nanowires and nanowalls grown on aluminum substrates. Morphological and microstructural characteristics of these nanostructures have been analyzed using scanning electron microscopy (SEM) and high resolution electron microscopy (HRTEM). The presence of surface-adsorbed H þ , O 2 À , and OH À species on ZnO nanostructures has been established through secondary ion mass spectrometry (SIMS). The relative change in substrate coverage under varying reaction time has also been evidenced through SIMS and is in agreement with SEM observation. Compared to nanowires, oxygen adsorption on ZnO surfaces and subsequent oxygen in-diffusion are found to be prominent for the nanowall-like structures and are seen to be highest for nanowalls grown in lower reaction time. In contrast to nanowires, nanowalls are found to exhibit higher photocatalytic activity and this can be attributed to higher adsorption of oxygen. The photocatalytic activity of the samples under visible light is originated from the native defect-states and the photocatalytic efficiency is largely influenced by the surface-adsorbants. Control of surface adsorption characteristics of the nanowalls upon tuning wall thicknesses can lead to the development of futuristic efficient photocatalytic devices. V C 2015 AIP Publishing LLC.

Phillip F. Kane's long career with chemical analysis began in 1938 at the quality control laboratories of Standard Telephones and Cables Ltd., London. While there he studied part time at London University and was graduated in 1948. The following year he joined Laporte Chemicals Ltd., Luton, England, where he developed methods for trace determinations in hydrogen peroxide and organic peroxides. In 1957 he joined the Chemagro Corp. in Kansas City, Mo., to direct a group developing methods for the analysis of organophosphorus pesticides. Since 1959 he has been with Texas Instruments in Dallas and has concentrated his research efforts in the characterization of semiconductor materials. He is currently director of their Materials Characterization Laboratory. Mr. Kane has published a number of articles in Analytical Chemistry, Journal of Agricultural and Food Chemistry, and Chemical Technology. Co-author of the book "Characterization of Semiconductor Materials" and co-editor of the book, "Characterization of Solid Surfaces", he is also a contributor to "Standard Methods of Chemical Analysis" and "Annual Reviews of Materials Science". Mr. Kane is a member of the Society for Applied Spectroscopy (National President-Elect) and the Chemical Society (London) and a Fellow of the Royal Institute of Chemistry. He is currently serving on the Advisory Board of Analytical Chemistry.Graydon B. Larrabee has received his M.Sc.

“…Sir: Secondary ion mass spectrometry (SIMS) is establishing a place for itself among surface analytical techniques (1) largely due to its extreme sensitivity (2) (10™6 monolayer for some metals and some molecules), the detectability of all elements as well as isotopic and isomer sensitivity (3), the ability to access working surfaces (4) such as catalysts and electronic devices, and sensitivity to molecular and crystal structure in the outer two to three atomic layers of a material (5,6). The ability to ionize and detect large involatile and thermally fragile molecules deposited on metal surfaces (7,8) and matrix-isolated organic species (9) has also been demonstrated.…”
