Yttrium Orthoaluminate (YAlO3)

Yttrium Orthoaluminate (YAlO3)


Yttrium Orthoaluminate (YAlO3) is aslo referred to asyttrium aluminum perovskite (YAP), doped with Tm, Nd, Pr, Er and Cr. It is a single crystal simlar to YAG, which doped with rare earth and transition metal ions are widely used in laser  scintillation holographic recording, optical data storage ionization radiation dosimeter and high temperature superconducting thin film substrate.
