Description

The absorption and emission spectra and the luminescence kinetics of Mn4+:YAlO3, the potential crystal for holographic recording and optical data storage, were studied at room and liquid-nitrogen temperatures. The spectroscopic properties of Mn:YAlO3 were compared with those of Mn:GdAlO3, Mn:Y3Al5O12, and Cr:YAlO3. It was found that a single-site occupancy of Mn4+ ions in YAlO3 and GdAlO3 at room temperature changes to a multisite occupancy at low temperature. Possible reasons for such a transformation are discussed. The parameters Dq and B in Mn4+:YAlO3 were determined to be 2115 and 680 cm-1, correspondingly. copyright 1999 Optical Society of America
