Abstract
A method for making an artificial fluorescent precious stone, uses ZnS as base material, Au and Cu as activation agent which accounts for 1 X (10 to the power -6) - 5 X (10 to the power -6) (in wt.) of said base material, and adds Cu which accounts for (in wt.) 5 X (10 to the power -6) - 5 X (10 to the power -5) of said base material, said added materials can be AuCl3, CuCl2 and CuSO4 etc., common activation agent can be DyCl3, accounting for (in wt.) 1 X (10 to the power -6) - 1 X (10 to the power -5) of the base material, and CsCl as fluxing agent accounting for (in wt.) 0.5-1% of the base material. Said materials are passed through wet grinding by adding distilled water, baking, growing for 5-12 hours by gas-phase transport method at 1050-1200 degree C, HCl gas flow. The obtained precious stone is in hexagonal structure, transparent bright green, 5 hours in after glow and has no radioactivity.
Description
The invention belongs to the artificial crystal growth technology.
Hard mass is subjected to people with low basis, high quality and abundant colors to be liked, but the hard mass of fluorescent effect is not arranged at present as yet.
The making method that the purpose of this invention is to provide a kind of artificial fluorescent precious stone, this method technology is simple, the transparent bright green of the jewel of producing, it is also "dead" to reach 5 hours time of persistence.
For achieving the above object, the present invention adopts following technology:
Substrate material adopts ZnS, activator Au, Cu, and the add-on of Au is 1 * 10 of a substrate material weight
-6-5 * 10
-6, the add-on of Cu is 5 * 10 of a substrate material weight
-5* 10
-5, the adding form can be AuCl
3, CuCl
2, CuSO
4Deng, coactivator Dy, add-on is 1 * 10 of a substrate material weight
-6-1 * 10
-5, its effect can improve after-glow brightness, and the adding form can be DyCl
3, fusing assistant CsCl, add-on is the 0.5-1% of substrate material weight, can improve crystalline quality, prolongs time of persistence.Above-mentioned materials adds the distilled water wet grinding, oven dry, and 1050-1200 ℃ of following gas phase axle fortune method grown the HCl air-flow 5-12 hour.The jewel of making belongs to hexagonal structure, emmission spectrum 480-520nm, mohs hardness 4.5-5, refractive index 2.3-2.4, chromatic dispersion 0.157.
Below in conjunction with embodiment the present invention is specified.
Embodiment 1. takes by weighing substrate material ZnS 100g, activator CuSO
4Middle Cu concentration 8 * 10
-6, AuCl
3Middle Au concentration 3 * 10
