The paper 1 contains results of investigation of the structure and some properties of copper and molybdenum based composite materials and the processing parameters in their production via electron-beam evaporation/condensation. The present work has been done in connection with the necessity of improvement and repeatability of the properties of condensed molybdenum-copper materials, which partic...

The energy transfer mechanism between luminescent centers (LCs) and Er3+ in erbium-doped silicon-rich oxide (SROEr) films prepared by electron beam evaporation is investigated. Intense photoluminescence of the LCs (weak oxygen bonds, neutral oxygen vacancies, and Si=O states) within the active matrixes is obtained. Fast energy transfer from Si=O states to Er3+ takes advantage in the SROEr film ...

Nanostructuring for tailored optical functionality suffers from a lack of methods for large-area and low-cost fabrication. While electron beam lithography allows different complex shapes to be deposited onto the same substrate layer, the writing process is sequential and the fabrication is very expensive. Large-area methods, such as nanosphere lithography, [ 1 ] colloidal lithography using shad...

We demonstrate a method for fabricating a variety of nanostructured metallic thin films by using one simple approach based on the use of anodic aluminum oxide (AAO) membrane as masking template. Highly-ordered large-area metallic nanoporeor nanotip-arrays (e.g., Ni, Ag, Au), with various sizes and shapes, were deposited onto AAO membranes through e-beam evaporation. Free standing nano-patterned...

Abstract The method of pulsed electron beam evaporation in vacuum was first used to obtain CeF 3 nanopowder (NP). During NP production, a high rate the target (~ 7 g/h) and higher percentage collection (> 72%) were observed, both for fluoride previously obtained CeO 2 oxide. It found that produced contains two crystalline phases: hexagonal (95 wt.%, coherent scattering region ≈ 8 nm [Ce-O-F]...
