Results

Stage 1, year 2014

In this stage were designed, modeled, and realized materials as bulk glass, powders and coatings by sol-gel, MS and PLD methods.
The influence of pH, temperature, time on the sol- gel process was investigated, in aim of obtaining powders and desired thin films.
Were analyzed the properties of vitreous blocks materials, powders and thin nanostructured vitreous films, by using DTA, Raman, FTIR spectroscopy and UV-VIS, thermal analyzes and Vickers micro hardness.
Correlation structure - properties was done by using XRD, XRF, SEM + EDS, EDAX, and AFM.

Project Summary

Project Summary, including: specific innovation objectives and results, needs addressed, impact and potential benefits (up to 1 page)

The purposes of the proposal are the i) design, ii) modeling, iii) development, iv)prototyping of a) nano-structured layers with functional surfaces, b) interdependence between nano-structure and chemical-physical properties and c) ancient and recent thermal history and d) rest of related process parameters for a total new class of boro-phosphate nano-structured materials (nano-structured functional doped boro-phosphate glass) via chemical route, comprising sol-gel, coprecipitation and coacervate obtaining techniques together with new physical techniques, meaning femtosecond laser pulse deposition and treatment and radiofrequency magnetron sputtering. The vitreous matrix will comprise as network formers phosphorus and boron oxide, as modifiers and chemical durability increasers CaO or MgO together with ZnO. For the opto-electronic and magnetic properties small components as dopants will be added, comprising Fe2O3, V2O5, Bi2O3, 1d, 3d, 5d elements or/and rare earth. This complex nano-matrix composition is all new and original. The project proposes as a main research direction, the achievement of a new class of vitreous advanced nano-functional layers and multilayers, with complex magnetic and optical properties, by non-conventional methods. The new chemical and physical methods comparatively to the classical melting of glass have decisive advantages as: rigorous stoichiometric control, high purity of raw materials and of final nano-materials, fine adjusting of the composition in solution and after heat treatment, gain of new well-defined properties controlled by the process parameters, decreasing by hundred degrees of the thermal treatment temperatures, lack of the noxes releasing and high work security.
