Using Czochralski (CZ) pulling method, an Er 3+ /Yb 3+ -codoped NaY(WO 4 ) 2 crystal was prepared. Absorption spectra, emission spectra and excitation spectra of this crystal were measured at room temperature. Some optical parameters, such as intensity parameters, spontaneous emission probabilities and lifetimes, were calculated from absorption spectra with Judd–Ofelt...
