The spectroscopic properties of the trivalent europium ion in crystalline host crystals are compared. Special attention is given to the transitions observed in the absorption and luminescence spectra. The crystal field splitting of (2S+1)L(J) manifolds with a small total angular momentum J is described. Systematic properties of the crystal field effect are discussed.
