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.
