Electron and Ion Energy Scintillator Detector

(P201430394 20.04.2014)

Our scintillator devices are designed with a multilayer structure of several inorganic scintillators materials. Each scintillators layer, deposited with thin film technology (Gil-Rostra et al. Surf. Coat. Technol. 222 (2013) 144), consists basically of rare earths ions (Eu, Tb, Ce, …) doping insulating (SiO2, ZrO2, Y2O3, …) or semiconductors matrices (TiO2, ZnO, …). The color and intensity of the emitted light of the final device depends on the depth reached by the radiation (electron, ions) impinging on its multilayer structure. In particular, the color of the emitted light is mainly selected by the type of rare earth doping of the active luminescent layers, and its intensity depends on the doping level and film thickness of the active layers. The developed scintillator detectors may find application as beam monitors in materials science applications (SEM or SAM microscopes, ion beam implanters, equipment dedicated to XPS, AES, REELS surface science analysis), in medicine as 3D radiation dose monitors, or in fusion reactors as monitors of magnetohydrodynamic instabilities.

The invention relates to a method for producing dielectric and/or barrier layers on a substrate, characterised in that it comprises the following steps: (a) cleaning substrates, (b) placing the substrate in a sample carrier and introducing same into a vacuum chamber, (c) dosing an inert gas and a reactive gas into said vacuum chamber, (d) injecting, into said vacuum chamber, a volatile precursor that has at least one cation of the compound to be deposited, (e) activating a radiofrequency source and activating at least one magnetron, (f) decomposition of the volatile precursor by plasma, producing the reaction between the cation of the volatile precursor and the reactive gas at the same time as the reaction is produced between the reactive gas contained in the plasma with the cation generated from the target by cathode sputtering, thereby generating the deposition of the film on the substrate. The invention also relates to the device for carrying out said method.

Versatile and Economical Method of Manufacturing Mixed Oxides Thin Films

(P201230048 13.01.2012)


The process consists of the simultaneous deposition of a ceramic matrix, using a reactive magnetron sputtering source, and the evaporation of a metalorganic compound of at least one cation of the mixed oxide to be grown. The energy and strongly oxidizing plasma generated by the magnetron sputtering process is used to decompose the metalorganic precursor, leading to the reaction of the cation, coming from the metalorganic precursor, with the oxygen contained in the plasma, causing the deposition of an oxide film on the substrate. The metal is incorporated into the ceramic matrix in a proportion which depends on the relative speed of «evaporation» of the two sources involved.ormation of bone tissue without requiring the removal of the membrane.

It permits marking or recording motifs on surfaces whereon there has been deposited previously a fluorescent polymer layer through a procedure of plasma polymerisation of molecules of a colourant. The procedure combines the special characteristics of the polymer layers making them suitable for being capable of recording diverse motifs thereon, and the possibility of recording by laser or other techniques. Among such characteristics should be mentioned the possibility of a notable visual effect, including for thicknesses of 100 nm, the use of layers non-observable when illuminated with visible light, the high optical quality (transparency) thereof, or the facility wherewith they may be processed by subsequent treatments, including diverse laser treatments.
