Yttrium aluminium perovskite(YAlO3, name as YAP) single crystal is similar with Yttrium aluminium garnet(YAG) single crystal. An important crystal matrix material with excellent optical and physicochemical properties, the YAP crystal is a rare earth and transition metal ion doped crystal, which widely used in laser, scintillation, holographic recording and optical data storage, ionizing radiation dosimeters and high temperature superconducting thin film substrates.
