Luminescence spectroscopy of high-energy 4f11levels of Er3+in fluorides

Abstract

The 4f11 energy levels of Er3+ in LiYF4 in the spectral region 39000–65000 cm−1 have been studied. The agreement between experimental energy levels, obtained from luminescence excitation spectra, and calculated energy levels is good. Luminescence originating from high-lying energy levels has been investigated. Emission from the states 4D1/2 (∼47 200cm−1), 2F(2)7/2 (∼54700cm−1) and 2F(2)5/2 (∼63 300cm−1) is observed. 2F(2)5/2 emission occurs for Er3+ in LaF3, where the 2F(2)5/2 level is situated just below the lowest 4f105d state, but also for Er3+ in LiYF4, where it lies in between the two lowest 4f105d states.
