As-grown Ce: YA1O3( Ce: YAP) single crystal was annealed at 1680 C in H2 atmosphere. The phenomena including color changes, absorption spectra changes and fluorescence spectra changes were observed and analyzed. All results indicate that the H2-annealed Ce: YAP crystal contains both YAP phase and YAG phase.
