Definitions
- the invention relates to artificial gemstones.
- Gemstones especially gemstones, are made before they are held in the metal body of a piece of jewelry, sanded or sanded to the incident Spectrally decomposing and reflecting light, thereby brings about the brilliance and fire of a gem becomes.
- this sets a minimum size and purity ahead of the gem. So about two are suitable
- Third of the mined diamonds are not for production of gemstones by grinding them because either have too little physicality or depth or only industrial because of their color or inclusions have it recycled (for technical purposes).
- the diamond maintains the brilliance or shine all in that a large part of the in the gem incident light almost in the direction is scattered back from where it came from. This is achieved in that the light which is transmitted through the upper facets fell into the diamond crystal is reflected in the lower brilliant area and can emerge again through the upper facets.
- the Light is generated in at least two reflection steps mirrored by a total of about (180 ° ⁇ x °). The order the facet angle to each other must be the optical one Properties of the diamond / air interface wear so that the angle of total reflection never exceeded becomes.
- the angles of the light beam path are getting bigger than that of the total reflection angle. That is, the Light is reflected back upwards, on the other hand the light must shine on the top facets and the chalkboard impinging at such an angle that the light can leak.
- the diamond diamonds are not like that ground that the light is thrown back exactly in that direction from which it came (like it would be the case with the cat’s eye). Rather lies between incoming and outgoing beam an opening angle, which leads to the eye-catching reflexes. The exit angle is due to the dispersion for different wavelengths different.
- the dispersion is essential for the fire of the diamond of the light in the diamond that causes the light is broken down like a prism and then as Spectral colors are perceived by the eye.
- the object of the invention is to create artificial Gemstones obtained by vapor deposition large layers of gemstone, which despite the unfavorable dimensions, d. H. of limited strength these layers get an attractive appearance.
- This object is achieved with a gem solved that from a preferably tabular Carrier or substrate consists of one surface has at least one pyramid-shaped depression and preferably by vapor deposition gemstone layer obtained by the CVD or PVD method wearing.
- the gemstone- especially diamond layer one gemstone according to the invention has brilliance, must whose on the carrier, e.g. B. a silicon wafer Underside be designed accordingly, so that it is like a single-crystal natural diamond to reflect much of the incident Light comes.
- a silicon wafer Underside be designed accordingly, so that it is like a single-crystal natural diamond to reflect much of the incident Light comes.
- This can be done by an appropriate Pretreatment of the surface to be coated Silicon wafers can be achieved. After this pretreatment the silicon wafer has the necessary shape as Negative form on, so that the back or bottom the diamond layer that forms accordingly receives positive form.
- such materials are also suitable, such as precious metals, tungsten, molybdenum or hard metal, that can be coated well with diamond and in the surface of which incorporates a corresponding structure can be.
- Incorporation of the structure in the to be coated Carrier can either depending on its material mechanically, e.g. B. by grinding a certain Profiles, electrolytically or, in particular for a silicon wafer, chemical or plasma technology can be achieved by etching.
- isotropic as well as anisotropic processes are used.
- anisotropic etchant z. B. KOH. This base leads to the formation of pyramidal etching pits in the single crystal wafer.
- Etching mask can also be done using an isotropic etchant a pyramidal structure etched into a base become.
- a suitable composition of the etching solution can create the required angles of the pyramid. As mentioned above, should be a gradual mirroring by approximately 180 ° ⁇ x °, the angles of the Pyramid to be adjusted accordingly.
- edge areas of the carrier of the gemstone layer can have different pyramid angles than in the middle area can be set. But it is also possible that reflective surfaces (facets) on the underside align the layer with different angles, to be independent in this way the brilliance and the fire from each other.
- the angles of the facets are chosen so that the light in the Gem layer reflected back and forth several times is, causing a strong splitting of the spectral Colors is achieved.
- Orientations other than (100) or (111) Wafers are used. What matters is that targeted interaction of crystal orientation the gem layer and direction of the etching attack, to achieve an optimal optical effect.
- a polycrystalline, e.g. B. after CVD process produced artificial diamond layer are still unlike a diamond single crystal Grain boundaries present by a different Refractive index as additional refractive areas are taken into account.
- the grain boundaries advantageously in their structure, for. B. must be columnar to be positive To have an effect on brilliance and fire. In each Fall must be the influence of the grain boundaries in the optical Effect.
- the light can also are scattered back by the fact that the back or Bottom of the gas phase gem, especially CVD diamonds additionally z. B. by gold or titanium is mirrored. Then the reflection is easy by reflection on the gold or titanium surface.
- the surface of the artificial diamond layer is advantageous, which is subsequently ground into it.
- the angles in the bottom are modified Adjust exit conditions.
- Gemstone-coated supports can be used as gemstones in a conventional manner, e.g. B. in the metal body of a piece of jewelry.
- the one bearing the deposited layer of gemstone does not have to be flat his; it can e.g. B. be convex to artificial Gemstones in the shape of a cabochon or boutton to obtain.
- artificial gemstones especially diamonds not only with special optical Characteristics like brilliance and fire, but also with surface dimensions, e.g. B. by multiple dimensioning, win as with those in the Natural stones not nearly accessible are and also with other synthetic methods, in particular the high-pressure high-temperature technology from economic-technical Reasons are not available.
- the gemstones according to the invention can be used in the production its own due to the composition of the gas phase Body color (e.g. blue through boron or yellow through Nitrogen) are awarded, what their use in every conceivable piece of jewelry or every conceivable Embellishment with precious stones enables.
- the gem layer 1 has on the underside Variety of pyramid-shaped elevations 2 with one Angle "A" on and is at the top with a Octagonal facet cut.
- the carrier on which the gemstone layer is applied does not have to be the dimensions of the later gem to have. From a large support with Gemstone layer can be separated and made into one Gemstone can be processed or edited.
