Abstract
Persistent spectral hole-burning has been observed in Pr3+ doped yttria stabilized zirconia (YSZ) and used to measure the homogeneous linewidth (G{cyrillic}h). Holes can be burned only in the lowest crystal field component of the 3H4→1D2 transition of Pr3+ ions (6115 Å, inhomogeneous linewidth: ∼100 cm-1) and observed below 25 K. Homogeneous linewidth of the transition is found to be 155 MHz at 4.2 K and to have a T1.20±0.1-dependence. Such a temperature dependence is quite similar to that usually observed in organic-molecules-doped polymers and coupling of electrons to the two level system (TLS) is suggested for the phase relaxation process.
