Spectroscopic characterization of Er3+ in stabilized zirconia single crystals

Erbium-doped yttria-stabilized zirconia (YSZ) single crystals of 84ZrO2/16YO1.5 composition have been studied by electron paramagnetic resonance (EPR), optical absorption and photoemission techniques at temperatures between 10 and 680 K. At 10 K the Stark-structure of the 4I15/2 and 4S3/2 multiplets has been resolved and it corresponds to a statistical distribution of nearly-cubic octocoordinated (CN8) and trigonal hepta-coordinated (CN7) Er3+ ions. The 300 K spectroscopic properties are studied in the frame of the Judd-Ofelt theory. From the calculated radiative transition probabilities and the measured lifetimes the authors have determined the nonradiative transition rates and luminescence efficiencies, and compared them with previous results using YSZ of a different composition. The influence of the matrix composition on the spectroscopic characteristics of the Er3+ ion is discussed.
