摘要:
Die Erfindung gehört zum Bereich der Diamantenbearbeitung (Diamantenveredelung), die das Anfärben mit verschiedenen Farben betrifft. Die Erfindung kann in der Schmuckwarenindustrie Anwendung finden. Das Verfahren besteht darin, dass im Kristallgitter eines Naturdiamanten vom Typ la, der Verarmungstypen enthält, oder im Kristallgitter eines Naturdiamanten vom Typ la mit hohem Stickstoffgehalt, der mehr als 800 ppm Stickstoffbeimischung vom Verarmungstyp A oder B1 enthält, isolierte Stickstoffatome in der Substitutionsposition gebildet werden, und zwar vom Verarmungstyp C. Der den Verarmungstyp A enthaltende Naturdiamant vom Typ la wird in einem Hochdruckgerät bei einer Temperatur von mehr als 2150° C bei einem stabilisierten Druck von 6,0-7,0 Gpa ausgeglüht, dann wird er durch einen Elektronenstrom von 5x10 15 -5x10 18 cm -2 bei 2-4 MEV bestrahlt und dem Aushärten im Vakuum bei einer Temperatur von mindestens 1100° C unterzogen. Der Naturdiamant vom Typ la mit hohem Stickstoffgehalt, der mehr als 800 ppm Stickstoffbeimischung vom Verarmungstyp A oder B1 enthält, wird durch einen hochenergetischen Elektronenstrom mit einer Bestrahlungsdosis von mehr als 10 19 cm -2 bestrahlt und dem Aushärten im Vakuum bei einer Temperatur von mindestens 1100° C unterzogen. Es ergeben sich Diamanten mit einer Phantasierotfarbe, die für Brillanten mit festen NV-Färbungszentren bestimmt sind, die im Wellenlängenbereich von 400-640 nm absorbieren.
摘要:
A method of inducing biaxial particle alignment in a body of crystalline particles of a material such as a high temperature superconducting material, having anisotropic magnetic susceptibility so that at least a major portion of the crystalline particles have at least two crystalline axes generally parallel, comprises subjecting the particles to a magnetic field which varies cyclically relative to the body of crystalline particles with time, and which has an average magnitude which is a maximum in a first direction, a lower average magnitude in a second direction generally orthogonal to said first direction and a minimum or zero average magnitude in a third direction generally orthogonal to said first and second directions. Alignment of the axis of maximum magnetic susceptibility of the particles generally with the direction of maximum average magnitude and the axis of minimum magnetic susceptibility of the particles generally with the minimum or zero average magnitude direction is induced.
摘要:
A crystalline substrate (10) such as diamond, cubic boron nitride or silicon carbide is doped with a dopant atom such as boron, phosphorus or arsenic. The method includes the steps of creating a first damaged layer (14) containing vacancies and interstitial atoms in the crystal lattice of the crystalline substrate (10), implanting the dopant atoms under conditions to create a second damaged layer (18) separate from the first damaged layer (14) and containing the dopant atoms, and causing the dopant atoms in the second layer (18) to diffuse out of that layer (18) and into vacancies in the first layer (14) and thereby occupy substitutional positions in that layer (14).
