Fe3+ Ti+ doped Blue colored sapphire Al2O3 Single crystal ＆Ruby
lens
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+), 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.
