YAlO3
Yttrium aluminate (YAlO3, YAP) single crystal is an important crystal matrix material similar to YAG single crystal with excellent optical and physical and chemical properties. YAP crystals doped with rare earth and transition metal ions are widely used in lasers, scintillation, and holography. Recording and optical data storage, ionizing radiation dosimeters and high-temperature superconducting film substrates and other fields.
