Fe3+ Ti+ / Cr+ doped Blue / Green / Red/ Yellow colored sapphire Al2O3 crystal ＆Ruby lens for laser
1.About the color
The main component of sapphire is alumina (Al2O3). The simple alumina single crystal is transparent and colorless, but it penetrates into the growing sapphire by different color elements, thus making the sapphire crystals different colors.
When artificially doped with iron ions (Fe3+) and titanium ions (Ti+), the crystals will appear blue sapphire (Blue Sapphire).
When the crystal is doped with iron (Fe3+) and cobalt (Co2+), vanadium (V3+) the crystal will appear green.
( Green Sapphire)
When the crystal contains chromium ions (Cr3+), or (Ti+), the crystal will appear red and become to be Ruby.
When the crystal contains nickel ions (Ni3+), the crystal will appear yellow and become Yellow Sapphire.
Green Sapphire Sapphire, with its Mohs hardness score of 9, second only to diamond, is one of themost valuable and wearable of all gemstones. Famed for its brilliance and rich blue color, sapphireactually occurs in a wide range of colors, including pink, yellow and green.
Sapphire is every color ofcorundum except for red, which is ruby. This paper explores the use of artificial single-crystal sapphire for watch glass, particularly in applications requiring green laser resistance. Sapphire crystal is highly valued in watchmaking due to its exceptional hardness, scratch resistance, and optical clarity.
By customizing the size and shape of sapphire glass, manufacturers can meet specific design and durability requirements for luxury watches. The study focuses on the crystal's ability to withstand exposure to green lasers, which is crucial for ensuring long-lasting optical quality and structural integrity. Our findings show that artificial sapphire crystal provides enhanced durability and laser resistance, making it a reliable material for high-end watch glass applications, especially in environments exposed to intense light sources or extreme conditions.
