Other AbstractYAlO_3 (YAP) crystal has been widely investigated in various fields because of its favourable physical and chemical properties. In our research on scintillation crystal of Ce:YAP, a peculiar phenomenon of color change in YAP crystal was found. In this article, we studied this phenomenon by means of transmission spectra and found that different anneal conditions and different dopants could greatly influence the colors. Anneal in H_2 or Ce dopant could reduce the colors and anneal in atmosphere or Yb dopant could make the colors deeper. We think this color change should be ascribed to the electron trap O~- centers produced in crystal growth due to the charge compensation. The absorption effect of O~- centers lead to the change of the crystal transmission at about 400nm. All the phenomena could be reasonably interpreted with this model.
