Solid-state ozone synthesis by energetic ions
نویسنده
چکیده
We have synthesized ozone by irradiating thin solid ®lms of oxygen and oxygen±water mixtures with 100 keV protons, motivated by recent reports of condensed O3 on icy satellites in the outer Solar system. We measured the depth of the Hartley absorption band in the ultraviolet by re ̄ectance spectroscopy and used it to quantify the column density of ozone. We analyzed the results using a three-component (O, O2 and O3) model that successfully explains the ̄uence dependence of ozone production. Ó 1999 Elsevier Science B.V. All rights reserved.

Ozone Synthesis on the Icy Satellites
Condensed O2 and ozone on the surfaces of some icy satellites are thought to originate from the radiolytic decomposition of surface water ice by the impact of energetic magnetospheric ions, but decades of laboratory studies have produced no evidence for ozone from the radiolysis of pure water ice. Here we report for the first time the production of ozone in ice by 100 keV ions. Using a method t...
متن کاملCopper Oxide Nanoparticles Prepared by Solid State Thermal Decomposition: Synthesis and Characterization
In this paper, we have focused on the preparation and characterization of copper oxide nanoparticles by solid state thermal decomposition of copper(I) iodide in the presence of thiosemicarbazone ligands without the need for a catalyst, employing toxic solvent, template or surfactant and complicated equipment, which makes it efficient, one-step, simple and environment-friendly. CuO nanoparticles...
متن کاملEnergetic Tuning in Spirocyclic Conjugated Polymers
Precise control of the energy levels in a conjugated polymer is the key to allowing their exploitation in optoelectronic devices. The introduction of spirocycles into conjugated polymers has traditionally been used to enhance their solid state microstructure. Here we present a highly novel method of energetic tuning through the use of electronically active spirocyclic systems. By modifying the ...
