https://www.cryscore.com/application-range-of-sapphire-crystal.html Sapphire (a-Al2O3) is a multifunctional oxide crystal with excellent optical, physical, and chemical properties. In the field of optoelectronics, sapphire crystal is the preferred substrate material for manufacturing gallium nitride (GaN) light-emitting diode (LED); in the field of optical communication, sapphire crystal is not only used as a short wavelength active device, but also as a polarizer of passive devices; in the field of laser, sapphire is an excellent laser medium material (such as Ti: Al2O3, Cr: Al2O3); in the field of superconductivity, sapphire crystals can not only produce Y-series, La-series high-temperature superconducting films but also grow new practical MgB2 high-temperature superconducting films.
