AbstractA CaF2CeF3disordered crystal containing 1.06% of Er3+ions was grown by the temperature gradient technique. Optical absorption and emission spectra recorded at room temperature and at 10 K, luminescence decay curve recorded at room temperature, and extended x-ray-absorption fine structure spectra were analyzed with an intention to assess the laser potential related to the4I13/2→4I15/2transition of Er3+. In addition, the thermal diffusivity of the crystal was measured at room temperature. The analysis of room-temperature spectra revealed that the 4I13/2 emission is long-lived with a radiative lifetime value of 5.5 ms, peak emission cross section of 0.737times;10-20cm2, and large spectral width pointing at the tunability of the emission wavelength in the region stretching from approximately 1480 nm to 1630 nm. The energies of the crystal field components for the ground and excited multiplets determined from low-temperature absorption and emission spectra made it possible to predict successfully the spectral position and shape of the room-temperature4I13/2→4I15/2emission band. Based on the correlation of the optical spectra and dynamics of the luminescence decay, it was concluded that in contrast to Yb3+ions in heavily doped CaF2erbium ions in the CaF2-CeF3crystal reside in numerous sites with dissimilar relaxation rates. © 2017 Chinese Physical Society and IOP Publishing Ltd.
